fix(pdm): support lock-spec >=4.5

[betaboon]

We're now running into similar issues as #115.

I know this change is most likely insufficient, but unblocks us for now.

let's take this as a starting point for discussion :)

I have the same issue. This workaround let me move forward but I can't migrate to Bazel 8.

but I can't migrate to Bazel 8.

Because of these rules? There have been some recent Bazel 8 fixes, although they haven't been released to BCR yet.

When I ran into this issue at first, I started to use this workaround with git_override. To migrate to Bazel 8, I needed #133 and until this one (#122) is fixed, I won't be able to have both, am I? I could still apply a patch locally but I'm not that desperate =)

i think this workaround is far from correct. I'm not using pdm anymore, so i don't really have the motivation to finish this right now. so anyone that uses pdm: feel free to pick this up.

Agreed and I'm starting to doubt this is actually the source of my issue. I tried uv instead ofpdm but as soon as I upgrade to pycross 0.7.1 I get the same error:

To whoever comes here, I managed to migrate to uv following example from e2e/. No more issues.
