Import error when trying to run git-sim

[Adricu8]

I installed the package on a mac M1, following the required dependencies and no errors.
When running git-sim -h:

Traceback (most recent call last):

Hi there,

This seems to be a known issue when installing Manim via Anaconda. Check out this link:

https://docs.manim.community/en/latest/faq/installation.html#i-am-using-anaconda-and-get-an-importerror-mentioning-that-some-symbol-is-not-found

"This is because Anaconda environments come with their own preinstalled version of cairo which is not compatible with the version of pycairo required by Manim. Usually it can be fixed by running:

conda install -c conda-forge pycairo

"

Can you try that and let me know if it works for you? Also I definitely recommend not using the system Python on Mac as it can lead to issues. Please make sure you're installing Git-Sim with a Pip that is linked to a Python installed through Homebrew. The Pyenv (https://github.com/pyenv/pyenv) tool might help with making sure the correct version of Python is active.

Let me know how it goes!

@Adricu8 Any update on this?

[Adricu8]

Indeed, it was an issue with the anaconda install.
After running conda install -c conda-forge pycairo it worked! Thank you 👍
I will try with anaconda and without it, do you know why can anaconda lead to issues?

Glad it worked! As I mentioned in the comment above, this is a Manim installation issue and what they said at the link I sent is:

"This is because Anaconda environments come with their own preinstalled version of cairo which is not compatible with the version of pycairo required by Manim."

I will close this since you got it working!

It would be great to get any feedback from you in the future about using Git-Sim. Have a great week!
