Requests Introduction & Overview

Hi Chris, thanks for the tutorial :-) Getting to know bpython was already worth so much! I didn’t know it so far but it already helped me today to get an effortless look into some module functions!

Thanks so much Dominic! I’m really getting mileage out of bptyhon, its fantastic for inspecting elements.

Yeah, big ups on bpython. I’ve been using bpython since Dan Bader showed it back when he use to make YouTube vids;)

Hi @ll, what’s the best way to install bpython? I’m getting error on homebrew and pip3…

Hey Christ, why the bpython installation doesnt work? I tried in my Mac terminal and even in PyCharm terminal?

Hi @emalfiza. I’m sorry you are having trouble with bpython. What type of error are you getting? What version of Python do you have, is it a version from Python.org or a different distribution, and which version of macOS? I have had lots of issues of late installing libraries/packages and python itself, as I had to start over with a new drive (SSD) in my Mac. Two of the problems I had involved for one the inability to compile the version of the package on my machine, and the other had to do with not having certificates installed. For the compiling I needed to update Xcode libraries, which the error I got in the terminal walked me through. The other issue with certificates had to do with the version of Python not automatically installing those certificates, and needing to go into the folder where Python is installed and click to run, Install Certificates.command.

In general the best method of installing is using python3 -m pip install bpython, but it would help to know what errors you are getting.

Hey @ChristBailey grateful of your reply to the issue.

I have the Python3 3.8.0 version install in my MacOS Catalina version 10.15.2 and I have downloaded python3 from python.org.

I tried the commands that you have used in the HTTP requests module plus the python3 -m pip install bpython and as will as python3 -m pip3 install bpython, but no joy.

The errors that I get is really verbose:

By the way I really loved and enjoyed your tutorials.

Hi @emalfiza, It looks like you are having a gcc compiler issue, but I’m not positive. The section (error:invalid active developer path(....CommandLineTools)) is referring to it being unable to find those tools I think. If you recently upgraded to Catalina, it can sometimes remove the tools, or makes other changes so that they don’t work. There is a terminal command to re-install them. xcode-select --install Here is a thread with more about it I found. I hope this helps.
