pip/pip3 replacement source in ubuntu18

Regardless of whether it is pip or pip3, the method is the same, namely: create a pip folder, the code is as follows

mkdir ~/.pip
vim ~/.pip/pip.conf

Involved in vim, refer to the article: Vim Command Daquan

Enter the pip.conf file and modify the link after index-url= to be a domestic source (at the end of the article). If the download speed does not change, you can change the code after trusted-host= to be the same as index-url

[global]
timeout = 6000
index-url = http://mirrors.aliyun.com/pypi/simple/
trusted-host = pypi.tuna.tsinghua.edu.cn
