Question

sudo pip install django

16

这是我第一次尝试安装Django，当我运行它时，成功安装了Django-1.7.3，但我收到了以下警告。我找不到关于它们的任何信息，所以希望有人能澄清它们的含义，如果需要修复它们，我该如何去做？

谢谢！以下是我的终端输出

这些消息告诉您，在使用sudo命令之后，当前用户已更改为root，而root不是那些目录或其中一个父目录的所有者。

sudo -H会将$HOME环境变量设置为/root，可能会隐藏这些消息，但您现在这样做也完全没有问题。

我相当确定这些消息并无需担心，但总是好的看到人们正在阅读它们并确保安全。

另外，要验证此内容，您可以尝试：

$ sudo env | less

和

$ sudo -H env | less

并且注意$HOME和$USER这两个变量
