2. 解决方法

1. 用 ping 看看网络情况

$ ping www.baidu.com
PING www.baidu.com(240e:ff:e020:9ae:0:ff:b014:8e8b (240e:ff:e020:9ae:0:ff:b014:8e8b)) 56 data bytes

pip.conf 的内容：

[global]
proxy = socks5://127.0.0.1:1080
index-url = https://mirror.baidu.com/pypi/simple/
extra-index-url = http://mirrors.aliyun.com/pypi/simple/
trusted-host = 
    pypi.baidu.com 
    mirrors.aliyun.com                    

timeout = 120
