Question

当我尝试通过cmd行安装软件包时，使用Python遇到以下错误。它运行已经好几个月了，这是我第一次感到头疼，

以前有人撞过吗？

C:\>python -m pip install numpy

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

就您而言，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

尝试通过cmd行安装软件包时出错
