Hello @blu3r4y

Sugestion for this:

jobs:
  test:
    if: github.actor != 'actions[bot]'
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
        with:
          ref: ${{ github.head_ref }}

      - name: Set up Python 3.9
        uses: actions/setup-python@v2
        with:
          python-version: 3.9

      - name: Setup tests
        run: |
          pip install --upgrade pip
          curl -sSL https://install.python-poetry.org | python3 -
          poetry config virtualenvs.create false
          poetry install

The line poetry config virtualenvs.create false is here for dont create a virtual env in Ubuntu ;)

Thanks @IvanildoBarauna for the suggestion, that is a great trick.

I partially remember that the crucial pieces of my previous Gist were about sourcing to GITHUB_PATH and GITHUB_ENV because without that I had issues when trying to directly call scripts, python packages, and even the poetry binary. I have no system right now to test your script against that, but future readers might.

Hi @blu3r4y

I'm happy that I can contribute with others readers using your Gist, thanks.

I have a project that uses exactly this script structure, if you are interested in seeing how this works in the real world, here it is...

The following project below also has similar needs, but uses another method with python's "venv"
