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
