在 Windows 中，python 2.7，我升级了 pip，它显示:

In Windows, python 2.7, I had pip upgraded, and it showed:

Successfully uninstalled pip-8.1.2
Successfully installed pip-19.3.1

但是什么时候:

pip --version

显示:

我试图通过以下方式反转"到旧版本:

I tried to 'reverse' to the old version by:

pip install pip==8.0.2

它显示了同样的错误.

不确定是关于 python 版本的.

Not sure it's about the python version.

我该如何解决这个问题?谢谢.

How can I correct this problem? Thank you.

推荐答案

您尝试在旧版本上重新安装 pip 是对的；您的安装已损坏.

You were right with trying to reinstall pip at an older verion; your installation is broken.

我环顾四周，一致认为你应该这样做:

I've looked around and the consensus is that you should do:

python -m pip install -U pip == 8.0.1

然后

pip install -U pip
