Can't install Poetry project in editable mode

[raxod502]

I would expect this to work, but it doesn't:

% pipx install -e --spec git+https://github.com/sdispater/poetry.git poetry
ERROR: Error installing 'poetry from git+https://github.com/sdispater/poetry.git#egg=poetry': editable mode is not supported for pyproject.toml-style projects. This project is being processed as pyproject.toml-style because it has a pyproject.toml file and no setup.py. See PEP 517 for the relevant specification.
'/Users/raxod502/.local/pipx/venvs/poetry/bin/python -m pip install --editable git+https://github.com/sdispater/poetry.git#egg=poetry -q' failed

Use case: I want to develop a Python package using Poetry which provides a binary, and I want to install it in my local environment using pipx for development.

Workaround is to add the following to my shell configuration:

if [[ -d /path/to/project ]] &&
       (( $+commands[poetry] )); then
    function my-binary {
        (
            cd /path/to/project || return
            poetry run my-binary "$@" || return
        )
    }
fi

Thanks for reporting. Unfortunately this is out of pipx's control. This was a rather large oversight of PEP 517. pypa/pip#6434

I haven't tried this yet, but there might be a workaround with the --no-use-pep517 flag (pypa/pip#6434 (comment)).

Something like

pipx install --pip-args "--no-use-pep517" ...

Whatever the case, this should probably be documented somewhere in pipx so thanks for bringing it up. I haven't had the time to fully understand the implications, so I am not ready to write docs on this. If you end up spending some time reading up and experimenting, doc PRs are welcome.

to me it seems to be still not working:

Since support of PEP 660 was merged in pip (since version 21.3), this issue is no longer relevant - it just works given that pipx uses an appropriate pip vesion.

This issue can be closed as resolved
