You are using pip version 9.0.1, however version 10.0.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

您是否尝试过使用cmd行作为管理员在下面运行,
pip install virtualenv
virtualenv带有一个pip副本,它被复制到你创建的每个新环境中,因此virtualenv就是所有需要的。您可以尝试将virtualenv作为独立包单独安装。这对Windows用户来说实际上更容易。有关说明,请参阅https://virtualenv.pypa.io/en/stable/。

问题解决了! Python 2.7.13附带的pip存在问题,保存了这个文件(https://bootstrap.pypa.io/get-pip.py)然后命令'python get-pip.py'通过升级来解决问题。由于命令'python -m pip install --upgrade pip'本身给出了与上面提到的相同的错误。谢谢大家!
