No module named 'manimlib.__main__'

I followed the steps of the macOS installation cited in the README:

git clone https://github.com/3b1b/manim.git
cd manim
pip install -e .
manimgl example_scenes.py OpeningManimExample

But when I run the last command, this error appears:

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.7/bin/manimgl", line 6, in <module>
    from manimlib.__main__ import main
ModuleNotFoundError: No module named 'manimlib.__main__'

I don’t know how to solve it, but I suspect it might have something to do with the previous manim installation I had. I moved the manim folder to another directory when I cloned the new version. Don’t know how to fix this.

You might be running a different manimgl command or something?

Try installing manim in a virtualenv. I think something like this on macOS

git clone https://github.com/3b1b/manim.git
cd manim
python3 -m venv .venv
source .venv/bin/activate
python -m pip install -e .
manimgl example_scenes.py OpeningManimExample

Try reinstall it.

I had reinstall many times, but it’s still not work. Then I tried @niedong 's method, it’s work. Anyway, thank you!
