Issue

I am trying to create a package that includes a shell script that I would like to make available to any projects that install this package. https://github.com/ethanabrooks/poetry-issue is the package that I want to install. To set up the project that I want to install the package into, I run:

poetry new poetry-issue2
cd poetry-issue2
poetry shell

Then both

poetry add git+https://github.com/ethanabrooks/poetry-issue.git@main

and

poetry add ../poetry-issue

yield the same error:

poetry-issue2-fWI-Kq6B-py3.6 ❯ poetry add ../poetry-issue

Failed to add packages, reverting the pyproject.toml file to its original content.

If I remove the last two lines (the [tool.poetry.scripts] section), the package installs fine.
