Issue

Good day, I would like to report an issue using Poetry. I wanted to use Docker as the virtual machine and Poetry as a package manager yet when I execute poetry install

It returns me this stacktrace:

list index out of range

This is the pyproject.toml

This is my Dockerfile and docker-compose if it helps: Dockerfile

I have a solution for now, that I posted in #2139 . I will post it here as well since this issue came up first for me.

I have the same issue. for me I believe it is because of this portion of my pyproject.toml

packages = [
    { include = "bohemian", from = "src"}
]

I am mostly doing this, because my project is inside a src directory. This happens in CI when I add the pyproject.toml and poetry.lock into a container and run install, when my apps code isnt there yet. But it work when I install with

poetry install --no-root

and then don’t install or run poetry build until I add my code into the repo.

I ran in to this error, because I typed packages = [{ include = “./commands” }] instead of packages = [{ include = “./commands.py” }] pretty misleading error message.
