could not find setup.py in installable package

[gmabey]

I'm able to install this package in a regular pip environment https://github.com/markvincze/sabledocs

However, generating a .deb complains that the setup.py file is missing???

I don't know enough about python packages to say how that can be ... is this an fpm bug or a sabledocs packaging error??

See #1982
Unfortunately the work is stale by lack of feedback/reviewers

[gmabey]

Yep understandable.

[gmabey]

Is this the same underlying issue as is addressed in #2040 ?

[amdei]

Issue seems to be the same.
Although in #1982 I made attempt to solve it via pip wheel, not via build module from PyPA, as suggested in #2040.
