python - 尝试通过 cmd 行安装软件包时出错

问题描述

当我尝试通过 cmd 行安装软件包时，Python 出现以下错误。它已经顺利运行了几个月，这是它给我的第一个头痛，

有没有人碰到过这个？

C:\>python -m pip install numpy

rm -rf /usr/lib/python3.7/site-packages
python3.7 -m ensurepip
pip install --upgrade pip

在你的情况下删除

C:\Users\agryga\AppData\Local\Programs\Python\Python37-32\lib\site-packages\pip

然后运行

python3.7 -m ensurepip
pip install --upgrade pip
