一、pip簡介
Pip 是安裝python包的工具,提供了安裝包,列出已經安裝的包,升級包以及卸載包的功能。
Pip 是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安裝的套件也同樣可以使用pip進行安裝。
二、Linux下的來源配置
檢查pip.conf檔案是否存在
>> cd ~
>> mkdir .pip
>> ls ~/.pip
三、編輯來源
方案1: 直接編輯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、檢定對比
使用預設來源的速度:

相對而言,速度提升了不是一點半點,而是飛一樣的提升。
