无法为 python 安装此 manim 库

Cannot install this manim lib for python

我正在尝试安装 manim,(请参阅此处:https://github.com/3b1b/manim). I'm using python version 3.7.7. I've followed the steps of this video https://www.youtube.com/watch?v=ZltiKHFWmv8 until I tried to install the requirements.txt (https://github.com/3b1b/manim/blob/master/requirements.txt)。我在终端上收到此错误:

ERROR: Could not find a version that satisfies the requirement requirements.txt (from versions: none)

ERROR: No matching distribution found for requirements.txt

有人知道怎么解决吗?

确保您在命令中使用了 -r 参数,因此您使用 pip3 install -r requirements.txt

我尝试从 https://github.com/3b1b/manim as well, didn't work. Then I stumbled across Manim's community version (https://github.com/ManimCommunity/manim 安装它。它更容易设置并且有很好的文档。它对我来说就像一个魅力。
