我正在尝试安装一些库，但每次我想安装新库。我从命令行

遇到了这条消息

Answer 1

首先，请注意此消息是警告，而不是错误，并且imagekit软件包已在您当前的环境中正确安装。

现在关于警告：它告诉您当前环境包含夹层版本4.2.3和Django版本2.0.2，它们不兼容（夹层4.2.3需要django 1.8到1.11）。你提到你“正在做与django无关的事情”，那么，为什么你在这个环境中安装了django和mezzanine呢？如果那些是全局安装（在virtualenv之外）那么你做错了，你应该单独留下全局（系统）env并为你的项目使用virtualenvs，这样你就不会有破坏的依赖问题。

Answer 2

具有Django 2.2支持的Mezzanine 4.3.1 （直到发布Mezzanine v.5发行版为止）

您可以在需求中使用以下行

-e git+git://github.com/stephenmcd/mezzanine.git@9768b46f8377796d5d51d74db54589c9d3669a47#egg=Mezzanine # feat: Add Django 2.2 compatability (#1956)

或点子 pip install -e git+git://github.com/stephenmcd/mezzanine.git@9768b46f8377796d5d51d74db54589c9d3669a47#egg=Mezzanine
