Python-pip使用国内镜像加速下载

当pip显示下载超时的时候，请尝试：

pipinstall（要下载的包名）-ihttp://pypi.douban.com/simple

如果提示：The repository located at pypi.douban.com is not a trusted or secure host and is being ignored. If this repository is 

available via HTTPS it is recommended to use HTTPS instead, otherwise you may silence this warning and allow it anyways with 

‘–trusted-host pypi.douban.com’.
