Pip Install Requirements.txt

1. cd to the directory wherever requirements.txt is placed.
2. Stimulate the virtualenv.

Run the pip install -r requirements.txt within the shell.

Typically this requirements.txt file is located within the root directory of your project. Note we hold a line for every package, later a version number. That is necessary because as you begin developing your python applications, you will develop that application by particular versions of the packages within the mind.
