pip freeze loses structure from original requirements.txt

[brylie]

The original requirements.txt file contains

# local package
-e .

When running pip freeze > requirements.txt the above line is lost, and may be easy to overlook when committing the new requirements.txt file.

Is the -e . important for the project to work 'correctly', in the context of a reproducible data science workflow? If so, is there another way to define the -e . flag, so that it won't be accidentally lost when freezing additional project requirements?

Possibly related to #5

Closing since nothing we can do about this at the moment, it is a bug in pip freeze.

This should work once pip 19.0 is out:
pypa/pip#5031

Good to know there is an upstream issue. I am pretty novice to all of this. Thanks @pjbull!
