Django，python3，在安装时我得到：“父模块'setuptools'未加载” [英] Django, python3, on install I get: "Parent module 'setuptools' not loaded"

问题描述

我看到很多有关父模块''未加载的错误和建议，...

我没看到关于开箱即用的任何内容django 3.5。

I don't see any about specifically "out of the box" django 3.5.

如您所见，我使用python3安装了django。 5。

As you can see, I installed django using python3.5.

似乎可以与python2.7配合使用...

It seems to work fine with python2.7...

还有其他人知道解决此错误的方法吗？我是在我的环境中做的吗？

Is anyone else aware of a way around this bug, or something silly I did in my environment?

我使用的是debian Stretch而不是buster，但是我不确定是否准备升级。

I am using debian stretch instead of buster, but I'm not sure if I'm ready to upgrade yet.

推荐答案

在版本50的setuptools中发生了某些事情。

Something happened in version 50 of setuptools.

我们可以解决该问题。通过将setuptools降级到49.3.0（可能是pip降为20.2.1）

We could "solve" this problem by downgrading setuptools to 49.3.0 (and maybe pip to 20.2.1)

pip install setuptools == 49.3.0 和 pip install pip == 20.2.1

请注意，尽管这只是一个临时解决方案！

Be aware though that this should only be a temporary solution!
