繼上一篇《Python virtualenv安裝庫報錯SSL: CERTIFICATE_VERIFY_FAILED》出現的問題進行一個一勞永逸的操作
pip升級到7.0以后，在使用http鏡像進行包安裝及升級的時候往往會有如下提示：
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
解決辦法如下：
安裝時加入
–-trusted-host mirrors.aliyun.com
參數
pip install beautifulsoup4 --trusted-host mirrors.aliyun.com
在pip.conf中加入trusted-host選項，該方法是一勞永逸
[global] index-url = http://mirrors.aliyun.com/pypi/simple/ [install] trusted-host=mirrors.aliyun.com
