09/27/2018, 1:52 PMIt uses a python-setup subsystem:
Copy code
$ ./pants options --scope=python-setup | grep interpreter
python-setup.interpreter_cache_dir = None (from NONE)
python-setup.interpreter_constraints = ['CPython>=2.7,<3'] (from HARDCODED)
python-setup.interpreter_search_paths = [] (from HARDCODED)enough-analyst-54434

Copy code
10:31:48 00:02 [pyprep]
10:31:48 00:02 [interpreter]
10:31:48 00:02 [build-local-dists]
10:31:48 00:02 [requirements]
10:31:48 00:02 [cache]
