Create the "nearbyshops" App

I’ve got some issues when trying to create the app. It raised the error (django.core.exceptions.ImproperlyConfigured: Could not find the GDAL library (tried “gdal203”, “gdal202”, “gdal201”, “gdal20”, “gdal111”). Is GDAL installed? If it is, try setting GDAL_LIBR ARY_PATH in your settings. )

but when I set the GDAL_LIBRARY_PATH, it still raised the error. I’m working on Windows

Done, I finally could debug it!!! I had to add these: GEOS_LIBRARY_PATH = r’C:\OSGeo4W\bin\geos_c.dll’ GDAL_LIBRARY_PATH = r’C:\OSGeo4W\bin\gdal204.dll’

I’m using Spyder and have not been able to use any of these commands in the terminal, instead I’ve had to use the command prompt. I’m pretty stuck now on the “python manage.py startapp nearby shops” part, as the cmd prompt just opens the script and doesn’t create a folder - any tips for a Windows user?

Are you running your command prompt as admin? I’m going to find a Windows machine and follow my own instructions. Sounds like I have to include some extra steps for Win users.

I’m running this on Windows 10 and experiencing the same issues as Kevin.

error (django.core.exceptions.ImproperlyConfigured: Could not find the GDAL library (tried “gdal203”, “gdal202”, “gdal201”, “gdal20”, “gdal111”). Is GDAL installed? If it is, try setting GDAL_LIBR ARY_PATH in your settings. )

Not sure where to make the path changes; in the os environment, the venv, or the django manage itself.

I’m putting together some separate instructions for Windows users. Sorry you’re running into trouble. You could set the path in any of those places, or in the settings.py file. Also, you’ll get this error and similar if you have 32-bit python with a 64-bit gdal installation (or vice versa). I mainly work on a Mac, but can appreciate the majority GIS folks probably work in Windows. I’m currently trying to get a clean setup going on Win 10. I’ll update this tutorial when I have that finished.

Hi Jackie, I am getting this issue after database connection added in seetings.py file, conn = _connect(dsn, connection_factory=connection_factory, **kwasync) django.db.utils.OperationalError: received invalid response to SSL negotiation: - Is there anything I missed in setup?

Hi Justin, first thing to check would be if you have the right port configured. Postgres will default to 5432 but the would be different if you manually changed it, or if you have multiple instances running.

Hi Jackie,I am using windows and experiencing error same as above

error (django.core.exceptions.ImproperlyConfigured: Could not find the GDAL library (tried “gdal203”, “gdal202”, “gdal201”, “gdal20”, “gdal111”). Is GDAL installed? If it is, try setting GDAL_LIBR ARY_PATH in your settings. ). not sure where and how add path.

I am getting the errors as all the others are getting with this. I have checked my folder for any of these: “gdal203”, “gdal202”, “gdal201”, “gdal20”, “gdal111” But it seems like they are not installed. I have tried as much as I can but can’t get it to work.

Does me using Python 3.7 have anything to do with it? I know you said it is not compatible with QGIS but would that have an effect on this part?

Thanks

same error as most of others getting here

Hi Jackie, Do you have any updates on issues with GDAL on Windows machines? I just run into the same problem as rest of Win users.

Do you know whether this issue occurs also on Linux?

Thanks in advance for your help and have a nice day!

Hi maju1005

found solution from this link : stackoverflow.com/questions/49139044/geodjango-on-windows-could-not-find-the-gdal-library-oserror-winerror-12

I’m using a Mac and facing the issue when I type python manage.py startapp nearbyshops

The error I receive is:- Could not find the GDAL library (tried “gdal”, “GDAL”, “gdal2.3.0”, “gdal2.2.0”, “gdal2.1.0”, “gdal2.0.0”, “gdal1.11.0”). Is GDAL installed? If it is, try setting GDAL_LIBRARY_PATH in your settings.

Please help me, What should i do

I’m on mac and I was getting that error, now I’m getting an error saying it referenced a directory and can’t find an image. I don’t know what to do.

I ran “brew install gdal” on my mac, fixed this issue! The installion takes a while.

Getting this error. would love to get this fixed asap please!

django.core.exceptions.ImproperlyConfigured: Could not find the GDAL library (t ried “gdal203”, “gdal202”, “gdal201”, “gdal20”, “gdal111”). Is GDAL installed? If it is, try setting GDAL_LIBRARY_PATH in your settings.

For windows 10 users getting the GDAL not found error I found this specific solution using the link above to stack overflow. I added the block of path logic to the top of the settings.py project file just below the existing import os statement.

if os.name == ‘nt’: import platform OSGEO4W = r”C:\OSGeo4W” if ‘64’ in platform.architecture()[0]: OSGEO4W += “64” assert os.path.isdir(OSGEO4W), “Directory does not exist: ” + OSGEO4W os.environ[‘OSGEO4W_ROOT’] = OSGEO4W os.environ[‘GDAL_DATA’] = OSGEO4W + r”\share\gdal” os.environ[‘PROJ_LIB’] = OSGEO4W + r”\share\proj” os.environ[‘PATH’] = OSGEO4W + r”\bin;” + os.environ[‘PATH’]

I ran into the same issue of django.core.exceptions.ImproperlyConfigured: Could not find the GDAL library (t ried “gdal203”, “gdal202”, “gdal201”, “gdal20”, “gdal111”). Is GDAL installed? If it is, try setting GDAL_LIBRARY_PATH in your settings.

I’m using MacOS 10.1.6 High Sierra. Homebrew installed Python3.7.4. I used pyenv and pipenv to set python 3.6.8 in my virtualenv.

How the django find a gdal installed by GGIS?

After all, I used brew install glad. After it was done, python manage.py startapp was run without error.

I got the same issue (on win10 64 bits) python 3.8 . I have installed OSgeo4W64 on my system. To solve this issue just include the following in the settings.py of your project.

GEOTH_LIBRARY_PATH = 'C:\\OSGeo4W64\\bin' GDAL_LIBRARY_PATH = 'C:\\OSGeo4W64\\bin\\gdal300.dll'

hope it will help hose who like me became mad with it!

Hi Jackie, I got the same issue (on win10 64 bits) , I have followed this stack overflow solution stackoverflow.com/questions/49139044/geodjango-on-windows-could-not-find-the-gdal-library-oserror-winerror-12

I have installed OSgeo4W64 on my system. and added this block of code in the settings.py

import os if os.name == ‘nt’: import platform OSGEO4W = r”C:\OSGeo4W” if ‘64’ in platform.architecture()[0]: OSGEO4W += “64” assert os.path.isdir(OSGEO4W), “Directory does not exist: ” + OSGEO4W os.environ[‘OSGEO4W_ROOT’] = OSGEO4W os.environ[‘GDAL_DATA’] = OSGEO4W + r”\share\gdal” os.environ[‘PROJ_LIB’] = OSGEO4W + r”\share\proj” os.environ[‘PATH’] = OSGEO4W + r”\bin;” + os.environ[‘PATH’]

But I now get this error: OSError: [WinError 127] The specified module could not be found

How can I solve this issue ?

thank you @nosizwe31 your solution worked for me too on Windows.

Hi, I am stuck here.

I’m using Windows 10 64-bit.

Hi Rony. You’re going to have to be a bit more specific. What’s got you stuck?

Hi All, Pls. help me resolve this issue , I am using window 8.1 32 bit system and tring to run python manage.py startapp nearbyshops command to create app but getting following error: django.core.exceptions.Improperly Configured: Could not find the GDAL library (tried “gdal204”, “gdal203”, “gdal202”, “gdal201”, “gdal20”). Is GDAL installed? If it is, try setting GDAL_LIBRARY_PATH in your settings.

Hi indibhopal. Others have had the same issue. Please see the comments above.

Hi everyone, I’m late to the party. Yes, I hit the same wall but all your suggestions helped me get a workaround for me. I’m running Windows 10 Pro (64-bit) on a laptop, Python 3.7 (64-bit), PostgreSQL 64-bit, QGIS 64-bit. At the top of the settings.py file, right beneath the “import os” statement (like earlier posts indicated), I pasted all this stuff. My QGIS had installed OSGeo4 here “C:\Program Files\QGIS 3.12" but it wasn’t the embedded spaces. Even the official Django 3.0 install notes said it needs some OS environment path variables added. Simply pasting the following did the trick, to allow the: python manage.py startapp nearbyshops to run to completion. Time has passed. So Python 3.7 is now supported. Here it is:

GEOS_LIBRARY_PATH = ‘C:\Program Files\QGIS 3.12\bin\geos_c.dll’ GDAL_LIBRARY_PATH = ‘C:\Program Files\QGIS 3.12\bin\gdal300.dll’

if os.name == ‘nt’: # raw str path where QGIS Win 10 installer placed GDAL base. OSGEO4W = r”C:\Program Files\QGIS 3.12” assert os.path.isdir(OSGEO4W), “Directory does not exist: ” + OSGEO4W os.environ[‘OSGEO4W_ROOT’] = OSGEO4W os.environ[‘GDAL_DATA’] = OSGEO4W + r”\share\gdal” os.environ[‘PROJ_LIB’] = OSGEO4W + r”\share\proj” os.environ[‘PATH’] = OSGEO4W + r”\bin;” + os.environ[‘PATH’]

Hi,Ricky White and dthomas01, I tried as u suggested, my earlier error is gone but getting a new error as :OSError: [WinError 126] The specified module could not be found: would appreciate if anyone could help me to resolve this new problem. thanks in advance.

1. Since you are using an old Windows 32-bit, I hope you installed all 32-bit versions of the other stuff (PostgreSQL, QGIS, etc). Otherwise, you might get a mismatch.
2. I’m running QGIS version 3.12, the latest. So that’s why my paths show that number. Do you in fact have a gdal.dll file in your C:\Program Files\QGIS 3.12\bin\ folder? If not then just need to fix your paths. Otherwise, there is one last thing to try.

3. What I did to see which exact file the libgdal.py was choking on was to look at the very last portion of my Traceback error and notice that the error occurred in this file (C:\Users(myuserid)\Anaconda3\lib\ctypes_init.py) at a line of code within class CDLL() having function “def init” which contained this code block:

   if handle is None: self._handle = _dlopen(self._name, mode) else: self._handle = handle

The error occurred right at the dlopen() call. So I just added my own little print() command to tell me what the input value was for self.name like so:

    if handle is None:
        print("DEBUG> opening CDLL file=", self._name)
        self._handle = _dlopen(self._name, mode)
    else:
        self._handle = handle

Then retried the earlier failed: python manage.py startapp nearbyshops

When it errored again, I look way up top in the console for the first 10 lines of system responses and saw my “DEBUG> opening…” printed the name: gdal300.dll Yours might be different…can’t say. At least, pinpointing which file it cannot find is a step in the right direction.

Hi dthomas01, Appreciate your efforts,my print output=DEBUG> opening CDLL file=kernel32 , is it something to do with windows 8 32 os? kindly advise further.

Thank you jlrv16, You fix helped me with this error: django.core.exceptions.ImproperlyConfigured: Could not find the GDAL library (t ried “gdal203”, “gdal202”, “gdal201”, “gdal20”, “gdal111”). Is GDAL installed? If it is, try setting GDAL_LIBRARY_PATH in your settings.

Addidng the path in my settings.py as below. GEOTH_LIBRARY_PATH = ‘C:\OSGeo4W64\bin’ GDAL_LIBRARY_PATH = ‘C:\OSGeo4W64\bin\gdal300.dll’

But before that, after activating my virtual environment i installed GDAL into it as GDAL might be installed Globally and not inside your virtual environment using this, 1. python -m pip install C:/Users/Dlu2/Downloads/GDAL-3.0.4-cp36-cp36m-win_amd64.whl

Am not sure if this had anything to do with clearing the error but just a step i thought is worth mentioning. Am using windows 10

This fix error on my mac Thanks - rupaklama on Nov. 6, 2019

I ran “brew install gdal” on my mac, fixed this issue! The installion takes a while. when creating nearbyshops app

I spent a lot of hours dealing with this OSError error: [WinError 126]. Are there any other suggestions on how I can get rid of it?

Hi all, tried the same fix as above and basically am ending with the same os error: OSError: [WinError 126] The specified module could not be found. Could you please let us know if this issue is being approached by the extended team for an resolution?! It’s seems to be an issue for quite a while now(just over a year today…), thanks.

HI lesgod and George. Can you share more information? The full Traceback would be helpful so I can help you debug this code. Thanks

Hi Ricky, unfortunately i’m in between moving house right now and can’t really use my machine; counting on the others in this group facing the same errors to share that traceback; have you tried to replicate this tut on a Windows machine?!

I have macbook air and in this while installing postgis it is getting stuck at downloading in elapsed time 0.00.06. Can any one help why this is happening? i tried this postgis installation so many times on windows so please can any one really help me with setting.py whole structure of file.

A Mac user who adds another thank you to rupaklama on Nov. 6, 2019 for the suggestion to “brew install gdal”. That resolved the django.core.exceptions.ImproperlyConfigured issue and I was able to complete creation of the nearbyshops app.

thanks

UPDATE Ricky and George, This worked for me: stackoverflow.com/a/49159195/57952

Glad you got it working bloydkylen :)

Hi. I had same problem with the GDAL path error - Am using windows 10, Python 3.8.5. I only inserted the 2 lines following the BASE_DIR line below into settings.py. (NOTE: that my QGIS library is 3.10, not 3.12 as in above comments):

# Build paths inside the project like this: BASE_DIR / 'subdir'.
BASE_DIR = Path(__file__).resolve().parent.parent
GEOS_LIBRARY_PATH = "C:/Program Files/QGIS 3.10/bin/geos_c.dll"
GDAL_LIBRARY_PATH = "C:/Program Files/QGIS 3.10/bin/gdal300.dll"

Don’t know if you actually need the GEOS_LIBRARY_PATH line as the libgdal.py module only looks for the GDAL_LIBRARY_PATH?

There is most likely a better place to insert this path in settings.py as the comment in settings.py reads ‘# build paths inside the project like this: BASE_DIR / ‘subdir’.

But I have no idea where in this module to put it as I’m still quite new to Python. Under TEMPLATES - DIRS or APP_DIRS perhaps (only place I can see paths/dirs specified)?

Hi Jackie have we found the solution for the windows environment ? thank you stelios

thanks everyone. UPDATE Ricky, George ET AL, This worked for me: stackoverflow.com/a/49159195/57952 ALSO !!

you need to make sure that you follow the solution as per link but make sure that you put the additional settings.py part at the top of the said file.

import os
if os.name == 'nt':
    import platform
    OSGEO4W = r"C:\OSGeo4W"
    if '64' in platform.architecture()[0]:
        OSGEO4W += "64"
    assert os.path.isdir(OSGEO4W), "Directory does not exist: " + OSGEO4W
    os.environ['OSGEO4W_ROOT'] = OSGEO4W
    os.environ['GDAL_DATA'] = OSGEO4W + r"\share\gdal"
    os.environ['PROJ_LIB'] = OSGEO4W + r"\share\proj"
    os.environ['PATH'] = OSGEO4W + r"\bin;" + os.environ['PATH']

then all commands work! e.g. python manage.py startapp nearbyshops

Hi all, I was getting the same django.core.exceptions.ImproperlyConfigured: Could not find the GDAL library (t ried “gdal203”, “gdal202”, “gdal201”, “gdal20”, “gdal111”). Is GDAL installed? If it is, try setting GDAL_LIBRARY_PATH in your settings. error. Because there seems to be a huge amount of variation here, I will be very specific with the details on how I resolved this.

Date: 20-Jan-2021. OS: Windows 10, 64 bit. Python: v3.9.0. QGIS: 3.16

I did NOT install gdal or any of the other drivers separately, everything was done following the video, except for using the latest versions. As such I did not have an OSGEO4W directory. Instead all of these files are in the QGIS directory.

Using the excellent suggestions above, I added the following code to my settings.py file, right below ALLOWED_HOSTS = []:

import os
if os.name == 'nt':
    import platform
    QGIS = r"C:\Program Files\QGIS 3.16"

    assert os.path.isdir(QGIS), "Directory does not exist: " + QGIS
    os.environ['OSGEO4W_ROOT'] = QGIS
    os.environ['GDAL_DATA'] = QGIS + r"\share\gdal"
    os.environ['PROJ_LIB'] = QGIS + r"\share\proj"
    os.environ['PATH'] = QGIS + r"\bin;" + os.environ['PATH']

After that the python manage.py startapp nearbyshops command works fine, and python manage.py check returns System check identified no issues (0 silenced).

Ok so I am building this via Docker and I am getting the same error - could not find GDAL library

If I manually add the path for it to the file it says,

OSError: /code/C:\Program Files\QGIS 3.16\bin\gdal301.dll: cannot open shared object file: No such file or directory

I added that line after the allowed_hosts = [] and still, nothing. Not sure what is happening here.

Nvm, realized there’s a whole documentation on QGIS for containerized deployment.

I am using Mac and got this error when trying to startapp:

func = self._FuncPtr((name_or_ordinal, self))
AttributeError: dlsym(0x7ff31d441a70, OGR_F_GetFieldAsInteger64): symbol not found

Please help. Thanks.

I refer to my previous questions. and have tried different method but no clue. Since “OGR_F_GetFieldAsInteger64” is raised from the following ds.py, I simple comment that line of code. Now at least “python manage.py runserver” works. Will see what will happen next.

site-packages/django/contrib/gis/gdal/prototypes/ds.py”, line 71, in <module> get_field_as_integer64 = int64_output(lgdal.OGR_F_GetFieldAsInteger64, [c_void_p, c_int])

Hello, I hit the same wall as everyone above howere unlike everyone else I get this error : django.core.exceptions.ImproperlyConfigured: Error loading psycopg2 module: No module named ‘psycopg2._psycopg’ I don’t know how to fix it PS: I’m using windows 10 64bits and Python 3.8.7

@Orephia The psycopg2 library is notoriously known to be problematic in installation because of the compilation process that it requires. Have you tried installing pre-built binaries for your specific platform?

$ python -m pip install psycopg2-binary

@Bartosz when I try this command in my venv I get this error: Failed building wheel for psycopg2-binary, so I just copied the package into the venv

@Orephia There can be many reasons for failure, which can be hard to tell without seeing your specific error message. It should contain some clues as to what went wrong. Do you want to share it?

@Bartosz here is the full message i get when I try installing it:

@Orephia It appears that there’s no prebuilt binary available for your platform, and the pip command resorts to trying to compile the library from source code using the Mingw compiler. The error message suggests there might be some missing prerequisites and links to the official documentation at www.psycopg.org/docs/install.html for more detail. I’m afraid I can’t help you more with this. Sorry…

Hey Y’all, I’m running a MacOS Monterey (12.2.1) and am getting the “ImproperlyConfigured( django.core.exceptions.ImproperlyConfigured: Could not find the GDAL library (tried “gdal”, “GDAL”, “gdal3.3.0”, “gdal3.2.0”, “gdal3.1.0”, “gdal3.0.0”, “gdal2.4.0”, “gdal2.3.0”, “gdal2.2.0”, “gdal2.1.0”, “gdal2.0.0”). Is GDAL installed? If it is, try setting GDAL_LIBRARY_PATH in your settings” error that everyone hits. Qgis can run with the latest python3 version so I’m not sure why it’s still hitting this wall. I tried the “brew install gdal” and it installs fine but doesn’t fix the problem. This error message pops up when I try to run “python manage.py runserver”.

Kale OHara did you install also the gdal Python package:

(venv) $ python -m pip install gdal

Make sure that you’ve done this in your virtual environment, and that you can confirm that the package is accessible in the same environment as your Django app.

If you’re still running into the same error, maybe one of these answers can help?

Ran into the same error on windows 10 with QGIS 3.28.12 with the GDAL dll not being found. After several hours of searching for options, trial and error , I was finally able to resolve it using a combination of what dthomas01 posted and this post:stackoverflow.com/questions/71847139/solution-to-installing-gdal-proj-geos-in-windows-10-for-django-geodjango

Thanks for posting dthomas01, that helped put me on the right path!!

I’m struggling with this tutorial. I got the nearbyshops app working by adding: GDAL_LIBRARY_PATH = r’C:\Program Files\QGIS 3.36.0\bin\gdal308.dll’ and changing ENGINE’: ‘django.db.backends.postgresql’ in settings.py. Hopefully I can keep moving now.

I have also ran into the common problem that my program could not find the GDAL library (on a Mac). Running “brew install gdal” also solved my problem.

I am just leaving a comment to highlight that having to waste an hour to understand a problem has left me with a negative impression of this website.

I have loved the content so far, but it makes absolutely no sense to not re-do this content if people have been have the same problems for five years! Now, I don’t know if downloading QGIS was the right method or if I could have done something much simpler.

@Thierry Gagné thanks for mentioning, and for bumping this course back up on our priorities list for updates. You’re right that we should have already tackled updates for this course a while ago 😳

We’re actively working on getting older and outdated content up to date, but it takes some juggling to continue creating new content at the same time. Anyways, I’ll make sure to get this course slated for an update as soon as possible.

Thanks everyone for commenting and providing solutions!
