【原创】Python3踩坑记——升不上去的PIP

处理完连不上的MySQL，又遇见一个无法升级的PIP，而且过程很诡异。提示升级失败，但再点开编译器却显示是最新版，pip list还是显示旧版，PyCharm这都是什么毛病……

PyCharm提示PIP升级失败

再次点开提示是最新版

PIP List显示PIP依旧是旧版

自动更新更不上去，挠头，要不试试卸载重装？

python -m pip install -U --force-reinstall pip # 卸载并重装pip  #-------------------------------------------------- (venv) D:/Develop/Python/mengclaw>python -m pip install -U --force-reinstall pip Collecting pip   Using cached pip-20.0.2-py2.py3-none-any.whl (1.4 MB) Installing collected packages: pip   Attempting uninstall: pip     Found existing installation: pip 20.0.2     Uninstalling pip-20.0.2:       Successfully uninstalled pip-20.0.2 Successfully installed pip-20.0.2

本来以为就到此结束了，结果新建了个项目又出更奇葩的问题，重装完还是19.0

重装完还是19.0

搞我呢吧，强制升级走起。

再看PIP版本，pip 20.0.2，舒服了。
