MSYS2 - 安装 python moviepy

分类：编程问答

如何解决MSYS2 - 安装 python moviepy

我正在尝试在 msys2 mingw64 (Windows 10) 中安装 moviepy python 模块。

我尝试使用 pip 命令并编译源代码。 你能帮我吗？

注意：我不知道为什么但是

$ python -m pip install moviepy
C:/msys64/mingw64/bin/python.exe: No module named pip
命令失败。 
$ whereis pip
pip: /usr/bin/pip /usr/bin/pip3.8 /mingw64/bin/pip /mingw64/bin/pip3.8

这是pip install moviepy的输出：

经过Xiddoc的建议

python -m pip install moviepy 与 pip install moviepy

的输出相同

提前致谢， 克里斯·帕帕斯

解决方法

我找到了。

  1. 运行pacman -S mingw-w64-x86_64-python-numpy
  2. 下载源代码from here
  3. 从 setup.py 中删除 numpy 要求（第 81 行）
  4. 运行 python setup.py build 和 python setup.py install
