在Django项目中，Python说枕头没有安装，但已经安装了

Question

将Python3.8升级到3.9后，发生了此错误，并表示未安装pillow。我试图卸载和重新安装枕头，但它没有工作

我正在Windows10Pro上使用Django3.1

pip freeze的输出也被附加

以下是错误消息：

Answer 1

这是一个警告，因为旧版本的pip正在重命名无法删除的文件夹，将第一个字母替换为tilda~

在C:\..\python38-32\lib\site-packages中有一个名为~illow...的文件夹

当我删除那个文件夹并重新安装python -m pip Pillow时，它就工作了

我也有同样的错误，这个post解决了问题
