Django 没有命名的模块 'PIL' 仅在生产中

Question

我在尝试使用django admin上传映像时会出现错误

modulenotfoundError at/admin/home/home/image/16/change/

没有名为" PIL"

的模块

奇怪的是，只有当我使用Apache运行Django站点时，才会出现，当我使用sudo python3 manage.py runserver 0.0.0.0:80运行服务器时，它的工作正常。此外，当我激活Django的虚拟环境时，我可以运行import PIL。使用sudo python3 manage.py shell运行Django Shell时，我也可以这样做。当我运行pip3 freeze和pip3 list。

时，该软件包也已安装

另一个注意事项，我无法在我的django project/

中运行wsgi.py文件

我不确定会有什么帮助，但是这里有一些我认为重要的文件。

apache conf文件：

<VirtualHost *:80>
  Servername www.ubspy.org
  Servername ubspy.org
  DocumentRoot /home/ubspy/django/
  WSGIScriptAlias / /home/ubspy/django/ubspy/wsgi.py

您需要安装枕头lib。

pip install Pillow

Answer 2

如果已安装了Python的不同版本，请检查Apache是否使用Python3运行您的脚本。

有时，如果您仅为用户或环境安装软件包，则在运行脚本形成另一个用户或外部环境时，您会遇到此错误。据我所知，Apache与另一个用户一起运行脚本，这可能会导致问题。
