无法在virtualen下安装Django

Question

1. 当我键入命令：“pip install django”时，显示错误消息： 错误：

Could not install packages due to an EnvironmentError: [Errno 13] Permission denied

1. 当我尝试命令：“pip install django--user”时，显示错误消息： 错误：

Can not perform a '--user' install. User site-packages are not visible in this virtualenv. 

我想在我的Mac上安装virtualenv下的Django，但是正如总结所示，我的许可被拒绝了，我确定我是root用户。你知道吗

Consider using the `--user` option or check the permissions.

我尝试了所有的方式，从谷歌搜索，我也重新安装我的MacOS， 同样的事情也会发生。你知道吗
