• (optional) I have used the develop branch
• I have searched the existing issues of NeMo-Guardrails

Python 3.11

Operating system/version

MacOS 15.1.1 (24B91)

NeMo-Guardrails version (if you must use a specific version and not the latest

Describe the bug

Installing the current develop branch with pip breaks as Poetry 2.0 has introduce breaking changes and backward incompatibility. This can happen to other projects that are setting NeMo Guardrails as dependency by referencing our github repo.

Steps To Reproduce

source env/bin/activate
pip install -e . --no-cache-dir

Expected Behavior

Should install the package without any error.

Actual Behavior

following repro steps would raise following error:

Getting requirements to build editable ... done
  Preparing editable metadata (pyproject.toml) ... error
