I can't seem to find the exact answer here. Is it possible to work without requirements.txt at all?

With pip (or pipenv), if I have a virtual environment, I can generate requirements.txt easily.

But, what if I have a project where we're trying to move to using pipfiles entirely. How do I initialize the pipfile from the existing virtualenv? In such a way that I can get rid of requirements.txt

pipenv pip virtualenv

This worked for me:

  1. rm Pipfile
  2. rm Pipfile.lock
  3. source path/to/venv/bin/activate
  4. pip freeze > requirements.txt
  5. pipenv install -r requirements.txt
  6. rm requirements.txt
  7. Rule the world

-- In english:

  1. Delete or rename Pipfile and Pipefile.lock
  2. Activate the virtual env
  3. Use pip freeze to create a requirements.txt file
  4. Use pipenv to install from the requirement.txt file. This initializes the Pipefile as well
  5. Delete the requirements.txt file
  6. Grab a coffee

The generated Pipfile will be version locked, but easy to edit.
