Manim: import readline is failing

[samern92]

I am trying to run examples_scenes.py and it threw a ModuleNotFoundError when it tried to import readline. This should be easy to resolve - just pip install readline right? Nope. readline apparently doesn't work on Windows, and I got this strange follow-up error below. I don't know what to do at this point. Help?

c:\Tensorexperiments\manim>python -m manim example_scenes.py SquareToCircle -pl

Found a fix! Apparently the correct thing to do on Windows is

pip install pyreadline

This requirements should be added in the readme.md and requirements.txt.

Should be fix with this pull request: https://github.com/3b1b/manim/pull/672
