在Django项目中，Python表示未安装Pillow但已安装 [英] In Django project, Python says Pillow is not installed but it is installed

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.
