You are using pip version 19.0.3, however version 20.0.2 is available.
You should consider upgrading via the ‘python -m pip install --upgrade pip‘ command.

方案一：

设置延迟时间

命令：pip --default-timeout=100 install XXX 

方案三：

在pip安装路径下，创建python文件（.py）

import os  
ini="""[global] 
index-url = https://pypi.doubanio.com/simple/ 
[install] 
trusted-host=pypi.doubanio.com 
""" 
pippath=os.environ["USERPROFILE"]+"\\pip\\" 

if not os.path.exists(pippath):  
    os.mkdir(pippath)  
with open(pippath+"pip.ini","w+") as f:  
    f.write(ini)  

在cmd上运行这个python文件，之后再用pip install命令安装速度非常快。
