I had wanted some confirmation about a interaction between lockfiles and

PANTS_PYTHON_REPOS_INDEXES

or the

python-repos.index

setting. I assume that custom indexes have to be set during the

pants generate-lockfiles

step to be used. If a custom index is set by

PANTS_PYTHON_REPOS_INDEXES

env var or a

pants.ci.toml

only during the

pants package

step, it will not be used for retrieving the locked dependencies. Is that a correct understanding?

Hey I do set-up extra index during lockfile generation. I do think that’s how it’s supposed to work. But again I would leave it to some core maintainers to answer it.

That is correct - the lockfile generator needs to see the custom indexes

Thank you both for the confirmation!
