python infer: I have situation (still debugging) where pyqt5 is used in tests, and there are two PyQT5 libraries (PyQt5 and PyQt5-Qt5) that provide the relevant modules. Leaving Pants to auto-infer

from PyQt5 ...

did not choose the required one,

PyQt5-Qt5

so i added a module Mapping

python_requirements(
    module_mapping={
         "PyQt5-Qt5": ["PyQt5"],
    },

but of course, I need the "other"

PyQt5

library also to be included in the test. Any suggestions to how I resolve this .. I am holding off adding static dependencies for each BUILD file, as there aremore than a handful. is there another technique other than statically adding the two (non-inferred) dependencies ?

I’d consider using either the

requirements

field or

dependencies

in

overrides

on the

python_requirements

target so you get the second library when Pants infer a dep on the first library (not sure which is which here as I don’t know them). Example:

python_requirements(
  overrides={"PyQt5": {"requirements":["PyQt5", "PyQt5-Qt5"]}},
)

Keeping this information as close to the requirements target as possible as if you add it on the python_sources target, it becomes more difficult to maintain (easy to miss when looking at the requirements, or when adding another python_sources that would need it as well etc)
