I have a hunch I've just missed something in the docs or user guide, but, I'm a bit stuck trying to run a Python module installed into my repo's "universe of dependencies". Prior to using pants, I would have run

.venv/bin/python -m some_tool ...

. Is there a relevant target that I've missed?

Is this a module in some third-party requirement?

A third-party requirement

Are you trying to run it outside of pants? You probably need to

pants export

a virtualenv and then you could run it with

dist/<however/it/exports/the/venv -m some_tool

see https://www.pantsbuild.org/2.21/docs/using-pants/setting-up-an-ide

I'm hoping I can get pants to run it. Like,

pants run ...

. Of note, I'm using pants to install the dependency.

I think you can do this with a

pex_binary()

target whose

entry_point

field is set appropriately

Mm, thank you! Will give that a try

Keep in mind that this will build a pex and then run it, so it won't be fast

If it is the default entry point of the package, you can also do something like

pants run 3rdparty/py#black
