Cannot uninstall 'ipython

在ubuntu上更新ipython3时，在终端上报错：“Cannot uninstall 'ipython'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.”

解决办法：使用下面命令进行强制更新即可。亲测可用
sudo pip3 install --ignore-installed ipython --upgrade
