Re: pip requirements file
Yes. There is. I have been in need of this for a while until I found out. 2 steps: - pip install pip-chill - pip-chill The list will only have what you directly installed and will not list itself, which is pretty neat. The only thing you'll notice is that it's not alphabetically arranged. Cheers.
