I am confused by https://www.pantsbuild.org/docs/reference-python-setup#section-resolve-all-constraints .... true/false is clear enough (I think....) but the other options are not clear, is

always

the same as

true

and is

never

the same as

false

what about

nondeployables

, what does this option value mean?

Everything but

never

==

True

and

never

==

False

. This is a deprecation transition wart. The non-bools will be removed in 2.6.x:

$ ./pants --python-setup-resolve-all-constraints=never -V
19:36:07.00 [WARN] DEPRECATED: python-setup resolve_all_constraints non boolean values will be removed in version 2.6.0.dev0.

Instead of 'never' use False.
19:36:07.08 [WARN] DEPRECATED: python-setup resolve_all_constraints non boolean values will be removed in version 2.6.0.dev0.

Instead of 'never' use False.
19:36:07.10 [WARN] DEPRECATED: python-setup resolve_all_constraints non boolean values will be removed in version 2.6.0.dev0.

Instead of 'never' use False.
