Question

当我尝试使用pip安装matplotlib库时遇到了这个问题。然后我发现即使尝试安装其他库，该错误仍然仍然发生。

我的python安装路径- C:\Program Files\Python38\python.exe

我做到了-PS C:\Users\mihir> pip install matplotlib
在Windows Terminal中使用管理模式。在管理模式下以CMD提示符运行时，仍然显示相同的内容。

Answer 1

您必须不经意地升级了系统pip（可能通过async之类的方式升级了）

如果是，则需要重新安装pip：

pip install pip --upgrade

Answer 2

重新安装整个Python解释器对我有帮助！

使用Pip安装模块时出错
