权限错误，pip安装

Question

我刚开始使用新版本的 fedora，我正在尝试 pip install pew，以便我可以在一些虚拟 python 环境中工作。

pip 安装正确，至少我是这么认为的。

>>> pip -V
pip 7.1.0 from /usr/lib/python2.7/site-packages (python 2.7)

我知道版本有点过时，但我至少有pip。现在，当我尝试抓住长椅时，就会发生这种情况。

>>> pip install pew
You are using pip version 7.1.0, however version 8.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

在我看来，仅基于 "Permission denied" 位，我应该做这样的事情。

sudo pip install pew

在询问我密码后，我一遍又一遍地收到此消息。

etc...

谁能帮我弄清楚如何在我的新 Fedora 版本上正确进行 pip 安装？

Answer 1

忘了我什至问过这个问题，但我需要 "sudo su" 因为我试图将 python 软件包安装到需要 root 的地方。

更永久的解决方法是使用 pew 来管理我的 python 环境。在 pew 环境中，我将 python 软件包安装到不需要 root 的地方，然后问题就消失了。
