Is it possible to have different Python indexes for different resolves?

It is not today, no. This could be implemented though, if there was enough demand.

• Theres private support for this in 2.18 for internal reasons. That could be flexed to be external • You can generate lockfiles yourself (which we do) which provides ultimate flexibility

You mean not use Pants to generate lockfiles? How would that work?

Use

pex3 lock ...

🙂

And then manually add the dumb preamble header?

Or disable the Pants check 🙂 Not advocating for it as a long-term solution, but all the pieces are there

Seems like we could support this a little less annoyingly... 🙂

Currently we solve this with an alternative pants toml like so:

PANTS_CONFIG_FILES=pants.alt.toml pants generate-lockfiles --resolve=python-alt

It works great but it is slightly inconvenient since we have to invoke two

generate-lockfiles

commands. The reason for this is due to annoying local versions (e.g.

1.2.3+blabla

). If there is an alternative to handle those that would also solve the issue for us but AFAIK pip is very persistent in picking these "plus" versions.
