Manim BrokenPipeError:[Errno 32]管道破裂

Question

我正在尝试在Linux Mint Xfce计算机上安装Manim。每当我尝试执行：

manim example_scenes.py SquareToCircle -pl

我得到这个错误：

Media will be written to ./media/. You can change this behavior with the --media_dir flag.
Unknown input format: 'rawvideo'

BrokenPipeError: [Errno 32] Broken pipe

我试着跟着https://github.com/3b1b/manim/issues/669但没有任何效果。我升级了ffmpeg和我所有的其他东西，但我仍然得到同样的错误

我该怎么做才能让它工作
