python - 无法将 pip 9.0.1 升级到 9.0.3 - 已满足要求

Question

我正在尝试使用 pip install --upgrade pip 更新 pip，但在同一时间

$ pip install --upgrade pip
Requirement already up-to-date: pip in 
/Users/user/Envs/proj/lib/python2.7/site-packages
You are using pip version 9.0.1, however version 9.0.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' 
command.

如何更新？
