Troubles with package with local dependencies

Hello there!

I'm having a hard time with the particular configuration of my project. Here's what I have:

my_package/
├── src/my_package/
│   ├── some_code.py
│   ├── a_subrepo/
│       ├── src/a_subrepo/
│       │   ├── some_more_code.py
│       ├─ another_subprepo/
│       ├── pyproject.toml
├── pyproject.toml

my_package is a python package set-up with https://github.com/cjolowicz/cookiecutter-hypermodern-python. a_subprepo is a python package made with a bare poetry init and added to my_package with poetry add src/my_package/a_subprepo. The same deal with another_subprepo. It was added to a_subprepo (from its root directory) with poetry add another_subprepo.

The two subprepos are git submodules and I'd prefer to keep it that way, for faster development.

Now, I'm at the root directory of my_package and poetry install find the sub-repos as expected:

> poetry show
...
another_subrepo   0.1.0 src/my_package/a_subprepo/another_subrepo Another Subackage description
...
a_subrepo         1.0.0 src/my_package/a_subprepo               A Subpackage description.
...

The dependencies can be imported in the code and run just fine. But opening a nox session does not work:

❯ nox -s pre-commit         
nox > Running session pre-commit
nox > Creating virtual environment (virtualenv) using python3.8 in .nox/pre-commit
nox > poetry export --format=requirements.txt --dev --without-hashes
nox > Session pre-commit raised exception RuntimeError('line 60: \'another_subrepo @ file://<abs_path_to_another_subprepo>; python_version >= "3.8" and python_version < "3.11"\': Parse error at "\'python_v\'": Expected stringEnd')

During handling of the above exception, another exception occurred:

The above exception was the direct cause of the following exception:

    raise RuntimeError(f"line {line}: {requirement_string!r}: {error}") from error

nox > Session pre-commit failed.

And indeed the offending line in the requirements.txt file is

another_subrepo @ file://<abs_path_to_another_subrepo>; python_version >= "3.8" and python_version < "3.11"

I fear that pip does not support local dependencies, but I can't be sure; I find it weird, because pip install <path_to_another_subrepo> works just fine.

Any ideas? Thanks in advance!
