#安装pip
    tar -zxvf pip-9.0.1.tar.gz 
    cd pip-9.0.1
    python setup.py install

再执行`pip --version`，提示下面的异常

[root@ceshi187 pip-9.0.1]# pip --version
    Traceback (most recent call last):

    pkg_resources.DistributionNotFound: The 'pip==7.1.0' distribution was not found and is required by the application

解决方案是

1.  使用`easy_install pip==7.1.0`
2.  然后再安装`easy_install pip==9.0.1`
3.  然后删掉`rm -f /usr/local/lib/python2.7/site-packages/pip-7.1.0-py2.7.egg`
4.  问题就这么解决了，虽然不知道为什么会这样
