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.

回答1:

You have to run it with sudo unless you are using a virtualenv. The problem is that you don't have the permission to change that module. With sudo, you are giving administrator's permissions to update it.

sudo pip install --upgrade pip

The Error

OSError: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/pip-8.1.2.dist-info/DESCRIPTION.rst'

showed that you are not allowed to upgrade pip as a regular user, You have to run it as sudoer

sudo pip install --upgrade pip

Windows:

1) Close the current command prompt window.

2) Open it again, but as admin: right click and choose: "Run as administrator"

Linux or Unix:

Start the command with "sudo" as Tim and Haifeng mentiond.
