You are using pip version 8.1.1, however version 19.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
但是执行 pip install --upgrade pip 更新的时候依然执行不了。
原因时低版本的pip有bug.
所以去 加代理去 https://pypi.org/ 下载最新的pip安装包pip-19.1.1.tar.gz 然后解压,执行python setup.py install.
将这个新版本安装成功。
之后在去用pip安装就没有问题
