pip-compile on 1.10.2+ fails to handle mypy; >= '3.2' on python 2.7 #635
Description
I believe this is related to how environment markers are handled.
With requirements.in of:
mypy >= 0.560; python_version >= '3.2'
On python 2.7, run:
pip-compile --no-index --rebuild -v requirements.in
Produces:
Using indexes:
---snip---
ROUND 1
Current constraints:
mypy>=0.560
Finding the best candidates:
found candidate mypy==0.560 (constraint was >=0.560)
Finding secondary dependencies:
mypy==0.560 not in cache, need to check index

On python 3.5 and 1.11.0, it works, and output even retains the environment marker:
