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)The one non-obvious detail after that is Pants picks lowest-compatible for any version range.

09/27/2018, 2:32 PMhmmm... does this control what pyprep uses?
my problem is in pyprep using an old version i think, this:
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]

Seems like a bug.
