一、pip國內源鏡像:
阿里雲:http://mirrors.aliyun.com/pypi/simple/
中國科技大學:https://pypi.mirrors.ustc.edu.cn/simple/
豆瓣(douban):http://pypi.douban.com/simple/
清華大學:https://pypi.tuna.tsinghua.edu.cn/simple/
中國科學技術大學:http://pypi.mirrors.ustc.edu.cn/simple/
二、修改源方法：
1.臨時修改
可以在使用pip的時候在后面加上-index參數，指定pip源:
pip install --index https://pypi.tuna.tsinghua.edu.cn/simple requests
2.配置文件
Linux
①修改 ~/.pip/pip.conf (沒有就創建一個)， 內容如下：
[root@localhost .pip]# cat ~/.pip/pip.conf
[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
②使用：
[root@localhost .pip]# pip install xlwt

Windows:
①在我的電腦上的地址欄輸入：%appdata% ，然后回車；
②在里面新建一個名為 pip 的文件夾；
③在 pip 文件夾里面新建一個文件叫做 pip.ini ,內容寫如下即可。實際就是這么一個文件 ： %appdata%\pip\pip.ini。
文件內容如下：
[global]
timeout = 6000
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
trusted-host = pypi.tuna.tsinghua.edu.cn
④使用pyreadline庫，可實現Windows中python的tab鍵補全，安裝如下：
C:\Users\annie.wu>pip install pyreadline
