"Resolving wheels disallowed" error when using --lock and --only-binary

[sjincho]

I'm using pex 2.3.1 on Ubuntu 22.04.

If I create a lock file using:

pex3 lock create --output lock.json --only-binary ansicolors ansicolors

and run

pex --lock lock.json

it works w/o problem.

But running:

pex --lock lock.json --only-binary ansicolors

yields the following error:

Resolving wheels was disallowed, but the following project names are configured to only allow resolving pre-built wheels: ansicolors

In Pants 2.21.0, it seems like a change that uses pex to handle binary wheels was introduced.
pantsbuild/pants#20598

Due to this change, pants always passes both --lock and --only-binary flags, causing pantsbuild/pants#21077

Similar issue: #2389

Thanks for the report and repro. I will note, like #2389 this is a definitely bug, but also a weird use of a lock file. Since a lock is locked already, passing something like --only-binary ansicolors when using the lock doesn't make much sense. It would make a bit more sense if Pants didn't pass all these extra args when using a lock (as opposed to creating or updating one).

The fix for this is now released in Pex 2.4.1: https://github.com/pex-tool/pex/releases/tag/v2.4.1
