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

Answer 1

既然升级不行，就卸载掉旧版本，重新下载 9.0.1的安装包，然后python setup.py install 重新安装新版本即可。

Answer 2

这个更新可以无视，我装的是3.5.2，今天也是安装模块提升要更新，错误其实事其它错误。你想更新就照着输入python -m pip install --upgrade pip就行。
