Generating a minimal requirements.txt

Option 1 - via pip freeze

• create a clean virtualenv
• install only the modules needed to run project
• run pip freeze to generate a requirements.txt file
  • list of all installed packages and their versions

Option 2 - via pip-compile

• install pip-tools
  • pip install pip-tools
• create a requirements.in that lists all pip modules used by the project

# project dependencies
django
gunicorn

• use pip-compile requirements.in to generate a requirements.txt file

#
# This file is autogenerated by pip-compile
# To update, run:
#
#    pip-compile requirements.in
#
asgiref==3.2.10           # via django
django==3.1               # via -r requirements.in
gunicorn==20.0.4          # via -r requirements.in
