Hi I am getting Inflection module not found error while executing the entry point to run grprc server . The module is mentioned in the build file and was installed using pip install . Still getting error : Module not found

Can you provide more context? Are you trying to use remote cache or remote execution (which is hinted at by “grpc”)?

thanks

Good instinct, Asher. That indeed could be it. FYI this error message comes from Dagster, not from Pants. See https://www.pantsbuild.org/docs/troubleshooting#import-errors-and-missing-dependencies for the general guide on

ModuleNotFoundError

so sometimes 3rd party packages don't declare their external dependencies properly. see example: https://github.com/jazzband/django-axes/pull/803 in most case if that other dependency is installed to the virtualenv by other means (maybe the project has direct dependency on it) everything will work. but w/ pants it won't since pants won't see that dependency and hence won't include it.

@polite-garden-50641 I already mentioned the dependency in the BUILD file.

you can use the pants

dependencies

goal to see all the dependencies (including 3rd parties) that pants see for a given target, this is usually how I debug those issues, see if the inflection package is included in the output of the

dependencies

goal.

I have added the inflection dependency in the BUILD file and it gets detected but not showing up in the PEX binary

I have added the inflection dependency in the BUILD file and it gets detected

What do you mean - what did you do?

use

./pants dependencies

and give it the pex target instead of

::

i.e.

src/project/thing/foo:my_pex_target_name

@hundreds-father-404 what i meant was i externally defined that 3rd party dependency in the build file

where did you add

inflection

? To your

pyproject.toml

file?

@hundreds-father-404 No . In the build file
