创建并激活conda环境

conda create -n manim
conda activate manim

安装ffmpeg

conda install ffmpeg

配置pip清华镜像源

python -m pip install --upgrade pip
pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple

安装manim动画引擎

pip install manim
pip install manimgl   # 可选：安装manimgl

编写测试程序test_manim_0.py

from manim import *
class Try(Scene):
 def construct(self):
     c = Circle(fill_opacity=1)
     s = Square(color=YELLOW, fill_opacity=1)
     self.play(FadeIn(c))
     self.wait()
     self.play(ReplacementTransform(c, s))
     self.wait()
     self.play(FadeOut(s))
     self.wait()

生成视频动画

manim .\test_manim_0.py
