一、pip简介Pip 是安装python包的工具，提供了安装包，列出已经安装的包，升级包以及卸载包的功能。Pip 是对easy_install的取代，提供了和easy_install相同的查找包的功能，因此可以使用easy_install安装的包也同样可以使用pip进行安装。二、Linux下的源配置 检查pip.conf文件是否存在 >> cd ~ >> mkdir .pip >> ls ~/.pip三、编辑源 方案1： 直接编辑pip.conf sudo vi ~/.pip/pip.conf
[global] index-url = http://mirrors.aliyun.com/pypi/simple/ [install] trusted-host=mirrors.aliyun.com
方案2：
pip install turtle --trusted-host mirrors.aliyun.com
