这是一个非常烦人的依赖问题，因为cairocffi没有为Windows构建，你需要根据这里的说明安装额外的依赖：https://doc.courtbouillon.org/cairocffi/stable/overview.html#installing-cairo-on-windows 一个更快的解决方案是按照以下步骤操作：我使用了pipwin，它从一个非官方的仓库安装https://www.lfd.uci.edu/~gohlke/pythonlibs/#pycairo。

pip install pipwin

pipwin install cairocffi

此外，还请参考以下相关问题：在Windows上使cairosvg工作。
