继上一篇《Python virtualenv安装库报错SSL: CERTIFICATE_VERIFY_FAILED》出现的问题进行一个一劳永逸的操作
pip升级到7.0以后，在使用http镜像进行包安装及升级的时候往往会有如下提示：
Collecting beautifulsoup4 The repository located at mirrors.aliyun.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 mirrors.aliyun.com’. Could not find a version that satisfies the requirement beautifulsoup4 (from versions: ) No matching distribution found for beautifulsoup4
解决办法如下：
安装时加入
–-trusted-host mirrors.aliyun.com
参数
pip install beautifulsoup4 --trusted-host mirrors.aliyun.com
在pip.conf中加入trusted-host选项，该方法是一劳永逸
[global] index-url = http://mirrors.aliyun.com/pypi/simple/ [install] trusted-host=mirrors.aliyun.com
