我的Mac OS X 10.11.3上的pip安装完全出错。
当我使用pip -V时，我得到以下结果：
***:Desktop ***$ pip -V
pip 8.0.2 from /Library/Python/2.7/site-packages (python 2.7)
***:Desktop ***$
但是当我使用pip list时，我得到这个：
***:Desktop ***$ pip list
...
pip (7.1.2)
...
You are using pip version 7.1.2, however version 8.0.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
当我尝试更新pip时，会发生这种情况：
***:~ ***$ sudo -H pip install --upgrade pip

知道我如何找出出了什么问题/如何解决这个烂摊子吗？
你能从 github 下载 pip 8.0.2 然后从命令行安装吗？
$ wget https://github.com/pypa/pip/archive/8.0.2.zip
$ unzip 8.0.2.zip
$ cd pip-8.0.2/
$ python setup.py install
