Question

我使用this Ansible-Django堆栈将我的Django项目部署到AWS EC2实例。它工作了很长时间，但现在突然，我在部署时得到了以下错误。

似乎有一个新的setuptools版本未正确更新。

为什么要回滚setuptools？
为什么不安装setuptools 36.2.2？

在我的要求中明确指定setuptools的版本可以解决此问题，但由于我只是间接依赖setuptools，因此我不应该知道要保留哪个版本。

Answer 1

我不得不进入服务器并运行

$site_settings

然后我再次部署并且有效。

Pip正在回滚setuptools的卸载
