没有root权限的情况下升级pip

Question

我想在超级计算机中使用pip 8，但我没有root权限。从网上下载后PIP：

我做的：

You are using pip version 1.5.4, however version 8.0.3 is available. 
You should consider upgrading via the 'pip install --upgrade pip' command. 

它试图删除已有的点子，我不想（和我没有权限）。 ...我可以问我能做些什么？谢谢。

一些更多的更新：加入--user没有帮助：

myname@edison04:~/software/pip> python get-pip.py --prefix=~/local_python_lib/ --user 
ERROR: Can not combine '--user' and '--prefix' as they imply different installation locations 
You are using pip version 1.5.4, however version 8.0.3 is available. 
You should consider upgrading via the 'pip install --upgrade pip' command.

这将安装在某个位置PIP-1.5.4，但是我想用PIP 8.0.3，而不是...进一步当我找到安装的点子，并试图检查其版本...我认为这只是我的本地bin链接到点子1.5.4全球斌

我能做什么？谢谢

此外，使用虚拟ENV还没有解决这个问题：

建立后的virtualenv中，它也不会帮助...

/global/homes/k/key01027/dev/bin/pip 
(dev)key01027@edison08:~/software> pip install --upgrade pip

Python的虚拟环境解决这个问题，通过允许您在同一个系统上将项目的依赖关系与其他人分离。

大多数锁定的系统仍然提供virtualenv，如果没有，请联系您的系统管理员。
