pip install -e . doesn't work + 'manimgl' is not recognized as an internal or external command,

I tried it last night and it worked perfectly, but after a restart it doesn’t work, says:

manimgl is not a recocgnized internal or external command

SO I delete everything, reclone it and do:

Code and Error

pip install -e .

and I get:

WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.

i just got the same issue i solved it by reinstalling python (but only for the current user not all users) and then reinstalled manim u could try it and tell me if it works for you

You need to clone this repository through git, you should not download the .zip file.

That’s a bad way of packaging… Normally, it should be possible to install directly from zip file. Essentially

pip install https://github.com/3b1b/manim/archive/master.zip

should work.
