在Django项目中，Python表示未安装Pillow但已安装

问题描述

将Python 3.8升级到3.9后，发生此错误，并说未安装枕头.我试图卸载并重新安装枕头，但没有成功.

After upgrading Python 3.8 to 3.9 this error has happened and says pillow is not installed. I tried to uninstall and reinstall pillow, but it did not worked.

我在Windows 10专业版上使用Django 3.1.

I'm using Django 3.1 on a Windows 10 pro.

pip Frozen 的输出也已附加.

这是错误消息:

推荐答案

这是警告，因为旧版本的pip重命名了无法删除的文件夹，将第一个字母替换为tilda〜.

It's warning because old version of pip was renaming folders that it could not delete, replacing first letter with tilda ~.

在您的 C:\ .. \ python38-32 \ lib \ site-packages 中有一个名为〜illow ... 的文件夹.

In your C:\..\python38-32\lib\site-packages have a folder named ~illow....

当我删除该文件夹并重新安装 python -m pip Pillow 时，它就起作用了.

When I delete that folder and reinstall python -m pip Pillow, it's worked.

我有相同的错误，此帖子解决了问题.

I have same error and this post solved problem.
