Using uv with internal libraries fails with `No module named 'pip'`

[wsantos]

We are trying to implement UV in our pip line bot we are getting this error for one of out libraries:

error: Failed to build editables
  Caused by: Failed to build editable: file:///Users/wsantos/projetos/xxxxxx/xxxxxxx
  Caused by: Build backend failed to build wheel through `build_editable()`:
--- stdout:

--- stderr:
Traceback (most recent call last):
  File "<string>", line 12, in <module>
ModuleNotFoundError: No module named 'pip'

During handling of the above exception, another exception occurred:

    exec(code, locals())

How can I fix it, I see some others issues about it but none told how we can fix it.

Thanks! Is this a library you all control? It looks like it depends on "pip". Does it declare "pip" as a build requirement, in the pyproject.toml?

Yeap we control it, we don't have a pyproject.toml how should I do it, we do have setup.py

This is a surprising workaround:

➜  uv pip install pip
Resolved 1 package in 176ms
Installed 1 package in 16ms
 + pip==24.0

Add a pyproject.toml with something like:

[build-system]
requires = ["setuptools", "wheel", "pip"]
build-backend = "setuptools.build_meta"

(and keep your existing setup.py as-is)

Closing since @hauntsaninja suggestion is what you're looking for!
