python - Django SystemCheckError 说 Pillow 未安装，但 Pillow 已安装

Question

当我运行 python manage.py runserver ，一切开始都很好，但后来我得到一个 SystemCheckError说明 Pillow 未安装；但是，这台机器上肯定安装了 Pillow。

这是我收到的错误:

Performing system checks...

我在 Ubuntu 机器上运行它。有什么想法吗？

在您的代码中，如果您曾在任何地方尝试使用导入语句，如 import pillow或 from pillow import ... ，将这些语句更改为:

from PIL import ...

或者

import PIL

PIL 即不再维护 Python 图像库， Pillow 改为使用。为了保持向后兼容性，PIL模块名称用于导入。
