You can always uninstall and reinstall Python. Also make sure you are running your computer as an admin.您可以随时卸载并重新安装 Python。还要确保您以管理员身份运行计算机。

It happens because some of the installation packages have already left in your home directory which you tried to install python from there.发生这种情况是因为一些安装包已经留在您的主目录中，您试图从那里安装 python。 They are n the form of '.package' (eg '.matplotlib') and as they left in the home directory python first goes there when you call the package which needs permission.它们的形式为“.package”（例如“.matplotlib”），当它们留在主目录中时，当您调用需要权限的 package 时，python 会首先进入该目录。 You need to delete them (the ones that are NOT in the python directory.), And then each time that you call the package. Python will search for at your given PATH.您需要删除它们（不在 python 目录中的那些。），然后每次调用 package 时。Python 将在您给定的路径中搜索。
