win10，python3，certifi 不能卸载 导致安装meteva失败

[zhengkai15]

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。

pip install --user meteva --ignore-installed.
虽然报错，但是可以import。
