我正在运行红帽企业Linux（在AWS上）。每当我使用pip时，它都会警告我，我的点数已经过时，我需要通过执行pip install --upgrade pip来升级它。
但是，当我这样做时，它似乎没有任何效果，只是告诉我同样的事情。这是通告！
我该如何解决这个问题？见下文
$ pip install --upgrade pip
You are using pip version 6.0.8, however version 8.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Requirement already up-to-date: pip in my-virtualenv/lib/python2.7/site-packages
由于前面提到的pip install --upgrade pip`似乎不起作用，我只是尝试卸载并重新安装python-pip。当我这样做时，它告诉我它将安装pip 6.1.1.-1.21.amzn1。如何安装新版本？
$ sudo yum install python-pip

答案 0 :(得分：3)
你能从github下载pip 8.1.1然后从命令行安装吗？
$ wget https://github.com/pypa/pip/archive/8.1.1.zip
$ unzip 8.1.1.zip
$ cd pip-8.1.1/
$ python setup.py install
