推荐答案

看起来 setuptools>=58 中断了对 use_2to3 的支持:

It looks like setuptools>=58 breaks support for use_2to3:

v58 的设置工具更新日志

因此您应该将 setuptools 更新为 setuptools<58 或避免在设置参数中使用带有 use_2to3 的包.

So you should update setuptools to setuptools<58 or avoid using packages with use_2to3 in the setup parameters.

我遇到了同样的问题，pip==19.3.1
