python切换pip安装源的方法详解

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

四、测试对比

使用默认源的速度:
