3.使用pip国内源
python使用pip安装模块很方便,可是在国内官方源总是会间歇性的连接不上,其实python在国内也是有安装源的,比如豆瓣,下面是使用方法.
文件路径

linux

    ~/.pip/pip.conf

文件内容

    [global] 

    index-url = http://pypi.douban.com/simple 
    trusted-host = pypi.douban.com  

或者使用-i指令:

    easy_install -i http://pypi.douban.com/simple/ saltTesting 
    pip install -i http://pypi.douban.com/simple/ saltTesting
