sudo pip安装djang

Question

所以这是我第一次尝试安装Django，当我运行它时，它成功地安装了Django-1.7.3，但是我收到了下面的警告。我在网上找不到任何关于它的信息，所以我希望有人能澄清他们的意思，如果我需要修复他们，我该怎么做？

谢谢！下面是我终端的输出

macbook:~ Asif$ sudo pip install Django

这些消息只是告诉您，在发出sudo之后，当前用户已更改为root，并且root不是这些目录或父目录之一的所有者。

sudo -H将$HOME环境变量设置为/root，并且可能会隐藏这些变量，但您这样做是完全正确的。

我很确定这些信息没什么好担心的，但总是很高兴看到人们在阅读它们，并确保。

此外，要验证这一点，您可以尝试：

$ sudo env | less

以及

$ sudo -H env | less

注意$HOME和$USER变量
