Hello! First of all - thank you for building Pants...
# general
Hello! First of all - thank you for building Pants - it is a trully awesome tool. I'm evaluating the use case where all 3rd party packages need to be installed from the internal devpi index. This all works when I manually create a lock file, point a tool (like black) and run
./pants generate-lockfiles ...
However when I try to use a tool that relies on a default lockfile, I get this error: (in this particular case I was running
./pants package
against a

As it tries to download from https://files.pythonhosted.org it's clear that the resolve doesn't honor the internal package index. I've tried adding the following to my
config with no luck:

env_vars.add = [
Could you maybe point me in some direction where the problem may happen? Thanks very much in advance!
I attempted to walk through your situation a few days ago and just documented that here: https://github.com/pantsbuild/pants/issues/16328 See the bottom of the pants.toml diff where several tools have a
path configuration added. You'll need to do that for all tools you use and then
./pants generate-lockfiles
and then commit all the new lockfiles to your repo.
yes, as I mentioned in the post, I can indeed pin all the tools to my own locks and it works but my question is more about how can I get around the issue when a default lock is resolved incorrectly
From what I can tell, your backtrace indicates this is just another tool to fix like you have the others. This one here: https://www.pantsbuild.org/docs/reference-setuptools This is definitely cryptic for sure.
It'll continue to be tool lockfile whac-a-mole.
For what it's worth, you should be able to remove the
configuration you added if that was just to try to work around default lock file issues. Pants / Pex won't use Pip environment variables.

alright, thank you
