Python3.6 Constraints

[tcco]

What is the recommended python-setup interpreter_constraints for specifying python 3.6?

Have tried in both the pants.ini and python_library and python_binary definitions with compatibility

'CPython>=3.6' -> Defaults to 3.7
'CPython>=3.6,<3.7' -> Conflicting Targets
'CPython==3.6' -> Conflicting targets

Feel like I'm missing the mark slightly here.

You probably want 'CPython>=3.6,<3.7', and for simplicity of debugging, starting with just the pants.ini setting. It's very likely something else is going on here though. Can you run with the environment variable PEX_VERBOSE=9 exported and provide full output?

What version of pants are you using? is #6284 relevant to you?

Appreciate the insight. I had a clash with a root level BUILD file that was contradicting my sub directory BUILD. And am running pants 1.9.0.

Happy to close out as this was my own doing
