windows 10下pip install pip -U 报错，改用 python.exe -m pip install --upgrade pip成功！

windows 10下的python3.11 环境里，pip好久没更新，每次用pip的时候它都提醒升级，

这次顺手升级，执行

pip install pip -U

结果升级不成功，报错显示：

ERROR: To modify pip, please run the following command:
E:\py311\Scripts\python.exe -m pip install pip -U

[notice] A new release of pip is available: 23.1.2 -> 25.0
[notice] To update, run: python.exe -m pip install --upgrade pip

按照提示：

python.exe -m pip install --upgrade pip

问题解决！

顺手安装了akshare

pip install akshare
