ERROR: Cannot uninstall 'certifi'. 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

pip install certifi --ignore-installed

        如果解决不了的话还可以尝试： 

pip install xxx --ignore-installed certifi

        这里面我们可以看到两条指令都有ignore-installed关键字，其实我们回到这个报错信息就能明白了：由于'certifi'是通过distutils安装的，因此它的文件分布在多个位置，难以确定哪些文件属于它，因此无法完全地卸载它。 为了解决这个问题，你可以尝试使用pip命令重新安装'certifi'，然后再卸载它 

        除了这种方式，还可以直接更新，也就是upgrade

pip install --upgrade --force-reinstall certifi
