Error installing manim and running a test program

[kkin1995]

Describe the error

I installed ffmpeg from the APT package manager and PyOpenGL from pip3 in a virtual environment. Then, when I tried to install manim in the same virtual environment it gave the following error

However, in the end, it said that it successfully installed manim and its dependencies.

Then, I tried to run a simple program to see if it works:

But, it just keeps running with no errors (like it is frozen).

Code and Error

Code:

 class SquareImage(Scene):
 def construct(self):
square = Square()
self.add(square)

manimgl manim_test.py SquareImage -s

Error:

I have the exact same issue. I'm also using Linux Mint, and have no idea about what pangocairo is.

In my M1 Mac, brew install pango can solve this problem.

You can check your LaTex and FFmpeg .And the python edition should between 3.7 to 3.9 .Most of the problem is from here .

Here is some website for you to check: https://docs.manim.community/en/stable/installation.html https://docs.manim.org.cn/getting_started/installation.html http://3b1b.github.io/manim/getting_started/installation.html

Linux system also needs to install Pango .Please check has your installed Pango.

This should be in the installation notes for Macs.
