I followed this tutorial: https://www.youtube.com/watch?v=ZltiKHFWmv8 After, I ran the python -m manim example_scenes.py SquareToCircle -pl command through the Windows terminal, in the manim repo folder, and got an error. Here is the trace:

D:\Documents\Coding\Installations\manim>python -m manim example_scenes.py SquareToCircle -pl

I am using this version of manim: https://github.com/3b1b/manim/tree/3b088b12843b7a4459fe71eba96b70edafb7aa78

Now change line number 288 in file manim/manimlib/scene/scene_file_writer.py from fp.write("file \'{}\'\n".format(pf_path)) to fp.write("file \'file:{}\'\n".format(pf_path))

after that try to run manim again
