Manim: No module named manim

[Planeuge]

Hi ! So, I tried to install manim but ran into an issue: I have successfully installed pip, cairo, ffmpeg and sox (and updated latex), but when I try to run a file, I get /usr/bin/python: No module named manim so I guess manim didn't install where it should have (and with further investigation, it looks like it didn't install at all). So, I'm kinda lost, I have tried many things, but I'm a beginner so I don't know what I should be looking for. I've read that the installation instructions are outdated, so I've tried installing some other ways around but still nothing. As I've said, I'm lost, and don't really even what to say to get some help.

I hope I've been clear enough, thanks in advance !

PS: I've also tried with python3 and python3.7 in the command line, same problem.

EDIT: Forgot to precise I'm on Ubuntu !

I have the same problem on macOS. I am still trying various things but suspect there may be a regression that was introduced recently.

UPDATE: As suggested in another issue, these instructions do work for macOS – maybe you can adapt them for Ubuntu?

@Planeuge Somebody on the Discord server suggested you need to cd into the manim folder if you are running it as a Python module. You’ll have to find that folder, of course.

I've (finally) found that folder where manim is installed, but I guess I now have to indicate it, because it's not where it's supposed to be installed ? And if I'm right, how do I do that ?

I've also tried (as suggested) to cd into that folder and running python3 -m manim filename.py -pl (the file I tested was an example file, I just can't remember the name) but I still get the same error message, so maybe I just didn't understand what you/they meant ?

I really don’t know exactly what to do, as I do not have Ubuntu myself. Maybe you could join the Discord server and ask people in the manim-help channels?

And perhaps you could try checking out the Git repo yourself as suggested in the instructions I mentioned above. This seems to work better than installing it via a package manager.

Well, it was my "rescue plan", I wasn't sure I could manage to install manim with the cloning method, but I gave it a try after uninstalling my first installation, and it worked like a charm ! I spent more time trying to make the first method work than just using the second method, but I guess I got some experience. Thanks anyway !

Get an example file, like this one: https://github.com/zimmermant/manim_tutorial/blob/master/manim_tutorial_P37.py
I tried using "python3 -m manim pymanim_tutorial_P37.py Shapes -pl" and got the "No module named manim" error
Next I ran just "manim pymanim_tutorial_P37.py Shapes -pl" and it worked fine.

I guess if you install via pip3 you don't need the "python3 -m" before it (compared to cloning the project)?

Running in Manjaro with kde.
