通过 pip 安装 pptx 以解决 enthought canopy 错误

Question

我无法设置 pptx 以使用 enthought canopy（我使用的是 Windows 8）。

使用pip安装过程中出现以下异常。请注意，在异常发生之前，Pillow 已被卸载。这是我唯一认为出错的地方。

可根据要求提供完整的调试日志。当前在 canopy 中输入 import pptx 会产生：ImportError: No module named _util

我认为这只是目录不匹配的问题，但我不确定如何检查是否是这种情况

Answer 1

当 Canopy 是运行时我可以重现这个问题，但当 Canopy 是不是运行.

推测原因：_imaging.pyd 文件（它是一个 Windows .DLL）在使用时无法替换它。

所以退出 Canopy 并重试。

其他使用PIL的包会有什么后果，我不知道。
