pip3安装报错：Cannot uninstall 'six'. 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.

Cannot uninstall 'six'. 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.

解决方法如下：

sudo pip3 install --ignore-installed six

其他报错同理，更换six
