python -m pip install --upgrade pip
pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple

 上面这个遇到报这个, 需要更新pyyaml版本. 国内镜像不靠谱. 

class BaseLoader(Realoaderder, Scanner, Parser, Composer, BaseConstructor, BaseResolver): NameError: name 'Realoaderder' is not defined

 

使用官方镜像

python -m pip install --upgrade pip
pip config set global.index-url https://pypi.python.org/simple
