解决PIP更新时遇到的ERROR: Exception: Traceback (most recent call last)问题

今天更新PIP报错：

ERROR: Exception:

You should consider upgrading via the 'C:\Program Files\python\python.exe -m pip install –upgrade pip' command.

根据这里提示的命令安装，还是不行，报错还是这些

可恶，竟然在这套娃

于是上网搜到其他命令

python -m pip install -U --force-reinstall pip

结果

还是不行，在一篇帖子看到说关键还是网速问题

于是多换几个网重复命令

 终于解决了，呜呜~

留下没有技术的眼泪
