python3怎么看是否安装pip（Python3pip升级报错问题解决方法分享）

Python在安装第三方库时有这样的报错提醒：

ERROR: To modify PIP, please run the following command: C:\Program Files\python3-10\python.exe -m pip install --user --upgrade pip WARNING: Ignoring invalid distribution -irsearch (c:\program Files\python3-10\lib\site-packages) [notice] A new release of pip available: 22.1.2 -> 22.3.1 [notice] To update, run: python.exe -m pip install --upgrade pip

但是当你按照提醒执行命令时会继续报错，详细如下：
