方法一：手动指定源

在 pip3 后面跟-i 来指定源，比如用豆瓣的源来安装 web.py 框架：

pip3 install numpy -i https://pypi.doubanio.com/simple/

注意后面要有 /simple/ 目录

国内可用源：

阿里云 ：https://mirrors.aliyun.com/pypi/simple/

中国科技大学 ：https://pypi.mirrors.ustc.edu.cn/simple/

豆瓣(douban) ：https://pypi.doubanio.com/simple/

清华大学： https://pypi.tuna.tsinghua.edu.cn/simple/

腾讯源：https://mirrors.cloud.tencent.com/pypi/simple

方法二：更改默认源

需要创建或修改配置文件（ linux 的文件在~/.pip/pip.conf ， windows 在%HOMEPATH%\pip\pip.ini ），修改内容为：

[global]
index-url = http://mirrors.aliyun.com/pypi/simple/
[install]
trusted-host=mirrors.aliyun.com

如果不加后面的 install

则需要每次在命令后面加上 --trusted-host

方法三：手动设置延时

需要看包的大小，有时可以下载下来，有时会卡住

pip3 --default-timeout=1000 install numpy
