You are using pip version 8.1.2, however version 9.0.1 is available. 
You should consider upgrading via the 'pip install --upgrade pip' command.

我猜你安裝Python來的軟件包管理器（APT？）。因此，您對/ usr/*文件夾層次結構沒有任何用戶權限。使用'sudo'命令前綴（'sudo pip install ...'）可能會有幫助，但可能會導致其他問題（由於主文件夾不同，安裝路徑錯誤） –

嘗試。

wget https://pypi.python.org/packages/e7/a8/7556133689add8d1a54c0b14aeff0acb03c64707ce100ecd53934da1aa13/pip-8.1.2.tar.gz 
tar -xzvf pip-8.1.2.tar.gz 
cd pip-8.1.2 
sudo python setup.py install

它應該幫助

爲什麼要再次下載和安裝已安裝的版本？ –
