"The following modules are not found yet" error lists builtin modules

[Helveg]

The error can be ignored by entering N for the proposed finding of these modules on PyPI, but it shouldn't be thrown at all for builtin modules right?

(paperpy-dev) robin@robin-ZenBook-UX533FN:~/paperpy$ pigar
The following modules are not found yet:
  os referenced from:
    /home/robin/paperpy/setup.py: 2
  abc referenced from:
    /home/robin/paperpy/build/lib/paperpy/interfaces.py: 5
    /home/robin/paperpy/paperpy/interfaces.py: 5
  argparse referenced from:
    /home/robin/paperpy/paperpy/cli/__init__.py: 2
Some of them may be not installed in local environment.
Try to search PyPI for the missing modules and filter some unnecessary modules? (y/[N]) N

Could you provide a minimal environment to reproduce it?

[Helveg]

1. Create a new pyenv virtualenv
2. Clone git@github.com:paperpy/paperpy (don't worry it's a very small repo)

cd paperpy
pip install -e .
pigar

Please provide the following information:

• OS
• version of Python
• version of pigar

Maybe you can update pigar to try it again?

Having a similar issue, it seems to not be able to pick up on some directories... I have a directory labeled "core" which is imported using something along the lines of from core import example, and it throws this error.
