pex lock subset There is no lock entry for <package> in <lockfile> to satisfy the transitive <package>.

[lecardozo]

I'm trying to use the recently released pex lock subset subcommand to extract a subset of the dependency tree of an existing lockfile but I'm getting an error which I'm not sure is expected:

Command

$ pex lock subset --lock lockfile.lock -r requirements.txt
There is no lock entry for colorama in lockfile.lock to satisfy the transitive 'colorama; platform_system == "Windows"' requirement.

Initially I thought this was happening due to the lack of a --complete-platform specification — since there is a environment marker for a different platform associated with this dependency —, so I included the platform JSON file (generated by pex itself), but the error still happens.

Question

Is this expected behavior? Should the lockfile indeed have an entry for this dependency?

Extra

• The lockfile was generated by pants 2.23.0 (which I think uses pex 2.16.2 for generating the lockfile according to source)
• Pex (used for running the command) version is 2.32.1
• The lockfile was generated on a Mac
• The complete platforms was generated on a docker container to include only linux
• The lockfile itself
• Complete platforms used: linux-x86_64.json

@lecardozo this smells like a bug, but can you please provide the contents of requirements.txt? That's the missing repro data here.

Ok, this is enough:

:; pex3 lock subset --lock lockfile.json click
There is no lock entry for colorama in lockfile.json to satisfy the transitive 'colorama; platform_system == "Windows"' requirement.

I'm going to convert this discussion to a bug.

Ok, bug to track is #2683
Thanks for the report @lecardozo.

[lecardozo]

Thanks for checking @jsirois!

@lecardozo the fix is released in v2.33.1.
You can upgrade Pants to use this release (if needed), with these instructions: https://www.pantsbuild.org/stable/docs/python/overview/pex#setting-pex-and-pip-versions

Hopefully that answers this Q&A.
