Why not pip freeze?
pip freezeonly saves the packages that are installed with
pip installin your environment.
- pip freeze saves all packages in the environment including those that you don't use in your current project. (if you don't have virtualenv)
- and sometimes you just need to create requirements.txt for a new project without installing modules.
