我正在按照此处概述的步骤设置用于教育目的的数学动画。我必须弄清楚如何为 Python 3.7 配置所有步骤，但这并没有造成任何重大问题。但是，我现在遇到了我不太理解的错误，这似乎来自 pycairo 包（我在下面用粗体突出了错误）。我尝试按照此处列出的步骤修复错误，但是虽然我已经成功安装了最新的 pycairo 包（1.17），但我仍然遇到相同的错误。我有一些编程经验，但我是 python 的新手，所以我不确定如何解决这个问题。任何帮助将不胜感激。

我已经发布了下面的代码（粗体错误）：

看来您正在使用 anaconda。据我所知，在为 pycairo 构建轮子时似乎存在一些问题。可能您可以尝试手动安装 pycairo，然后在 anaconda 提示符下再次重新安装 manimlib。

conda install -c conda-forge pycairo

我有 pycairo 的问题。我已经完成了一步解决。

您需要确保正确版本的依赖关系。

要降级它们，首先卸载：

pip uninstall Pillow idna requests urllib3

然后你应该安装特定版本：

pip install Pillow==5.3.0 idna==2.6 requests==2.18.4 urllib3==1.22
