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.

我猜你安装Python来的软件包管理器（APT？）。因此，您对/ usr/*文件夹层次结构没有任何用户权限。使用'sudo'命令前缀（'sudo pip install ...'）可能会有帮助，但可能会导致其他问题（由于主文件夹不同，安装路径错误） –

尝试。

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

它应该帮助

为什么要再次下载和安装已安装的版本？ –
