pipenv Unexpected End Of File error when installing from a repository with both pyproject.toml and setup.py files

Issue description

When installing from a repository that has both a pyproject.toml and a setup.py via pipenv install -e git+ssh://[email protected]/teamname/[email protected]#egg=package-name pip correctly installs the wheel, but when pipenv goes to update Pipfile.lock, it fails. Installing with pipenv run pip install ... also works, but does not update Pipfile.lock.

Expected result

Pipenv successfully generates the Pipfile.lock, including the package installed from the git repo.

Actual result

The process fails with tomlkit.exceptions.UnexpectedEofError: Unexpected end of file at line 22 col 0.

Steps to replicate

The pyproject.toml file only has configuration information for black. So when get_pyproject in site-packages/pipenv/vendor/requirementslib/models/utils.py tries to load pyproject_data from the pyproject.toml file, it does not find a [build-system] section and raises the abover error; it thus misses the step a few lines down where get_pyproject checks if setup.py exists and can act accordingly.

A possible fix may be to change

        with io.open(pp_toml.as_posix(), encoding="utf-8") as fh:
            pyproject_data = tomlkit.loads(fh.read())

to

        try:
            with io.open(pp_toml.as_posix(), encoding="utf-8") as fh:
                pyproject_data = tomlkit.loads(fh.read())
        except tomlkit.exceptions.UnexpectedEofError as error:
            if not setup_py.exists():
                raise error

(Naturally a better fix exists where the user is told why it is that it failed instead of the cryptic unexpected eof error.)

This is related in terms of frustration to a pip bug with the same symptoms: https://github.com/pypa/pip/issues/7874 It may be that, by design, if a repo has a pyproject.toml file it should have a [build-system] section, but I did not find this documented anywhere. In my case, I'm no longer using black and can get rid of the pyproject.toml file, but that doesn't mean it won't break in the future with some other requirement for a pyproject.toml file.

Verbose output from pipenv command (with some details redacted, and the traceback simplified a bit because the above description comes from debugging in PyCharm and should require less mental effort than examining the traceback):

Courtesy Notice: Pipenv found itself running within a virtual environment, so it will automatically use that environment, instead of creating its own for any project. You can set PIPENV_IGNORE_VIRTUALENVS=1 to force pipenv to ignore that environment and create its own instead. You can set PIPENV_VERBOSITY=-1 to suppress this warning.

And I suppose the title describes more than the actual issue, which is that there is a pyproject.toml file but no [build-system] section, because the intent was to use pyproject.toml for a different tool, and to use setup.py for building the wheel and specifying its dependencies.

Jul 03 '20 03:07 hlongmore

I have confirmed that removing the pyproject.toml file from the package results in a successful install:

$ pipenv install -e git+ssh://[email protected]/teamname/[email protected]#egg=package-name 
Courtesy Notice: Pipenv found itself running within a virtual environment, so it will automatically use that 
environment, instead of creating its own for any project. You can set PIPENV_IGNORE_VIRTUALENVS=1 to force
pipenv to ignore that environment and create its own instead. You can set PIPENV_VERBOSITY=-1 to suppress this
warning.

I am running into this problem as well... Is there any workaround that doesn't involve deleting the pyproject.toml file? Can I switch to pure pyproject.toml (move all the relevant information from setup.py)?

Jul 20 '20 20:07 spott

ok, looks like switching to pyproject.toml only doesn't work...

pipenv.patched.notpip._internal.exceptions.InstallationError: File "setup.py" not found. Directory cannot be installed in editable mode: <dir> (A "pyproject.toml" file was found, but editable mode currently requires a setup.py based build.)

Jul 20 '20 20:07 spott

I filed another issue to track support for pyproject.toml-only packages in editable mode: https://github.com/pypa/pipenv/issues/5055

Apr 18 '22 20:04 jtbandes

I believe this should be resolved, could you checked @hlongmore ?

Aug 18 '22 13:08 matteius

I don't currently have a project that meets the test criteria; I'll see if I can get to it within the week.

Aug 21 '22 07:08 hlongmore

The original error posted by @spott was a pip error -- but we are on the latest pip=22.2.2 now which certainly supports this case -- I am willing to reopen this or address a new issue report if we find it is still an issue.
