pip-compile does not pick up pytest dependencies

[mlenzen]

Compiling with pytest in the input does not result in pytest's dependencies in the output.

Environment Versions

2. Python version: Python 3.7.4
3. pip version: pip 19.3.1
4. pip-tools version: pip-compile, version 4.2.0

Steps to replicate

1. echo 'pytest==5.2.4' >requirements.in
2. pip-compile requirements.in
3. cat requirements.txt

Expected result

#
# This file is autogenerated by pip-compile
# To update, run:
#
#    pip-compile requirements.in
#
pytest==5.2.4
py==...
packaging==...
attrs==...
more-itertools==...
atomicwrites==...

Hello @mlenzen,

Thanks for the report! Could you try --rebuild flag with pip-compile command? Sounds like your cache was corrupted. See related issues: #928, #835.

Yeah, that solved it.
