Using pip behind a work proxy with authentification, note that quotation is required for some OSes when specifing the proxy url with user and password:

pip install <module> --proxy 'http://<proxy_user>:<proxy_password>@<proxy_ip>:<proxy_port>'

Documentation: https://pip.pypa.io/en/stable/user_guide/#using-a-proxy-server

Example:

pip3 install -r requirements.txt --proxy 'http://user:password@192.168.0.1:1234'

pip install flask --proxy 'http://user:password@192.168.0.1:1234'

proxy = http://user:password@192.168.0.1:1234
