Misleading error message when Pipfile is removed

See original GitHub issue

Issue description

When I remove the file Pipfile.lock it fails with a traceback:

...
  File "/Users/messa/code/gh/naucse.python.cz/myvenv/lib/python3.7/site-packages/pipenv/utils.py", line 355, in venv_resolve_deps
    escape_grouped_arguments(which("python", allow_global=allow_global)),
  File "/Users/messa/code/gh/naucse.python.cz/myvenv/lib/python3.7/site-packages/pipenv/core.py", line 109, in which
    if not location and os.path.exists(location):
  File "/opt/local/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/genericpath.py", line 19, in exists
    os.stat(path)
TypeError: stat: path should be string, bytes, os.PathLike or integer, not NoneType

When I remove Pipfile it fails with another traceback:

  File "/Users/messa/code/gh/naucse.python.cz/myvenv/lib/python3.7/site-packages/pipenv/core.py", line 320, in ensure_pipfile
    project.create_pipfile(python=python)
  File "/Users/messa/code/gh/naucse.python.cz/myvenv/lib/python3.7/site-packages/pipenv/project.py", line 627, in create_pipfile
    config_parser = ConfigOptionParser(name=self.name)
  File "/Users/messa/code/gh/naucse.python.cz/myvenv/lib/python3.7/site-packages/pipenv/project.py", line 219, in name
    self._name = self.pipfile_location.split(os.sep)[-2]
AttributeError: 'NoneType' object has no attribute 'split'

Expected result

I would expect a proper error message that some required file is missing. I would expect such behavior from a high-level beginner-friendly software 😃

In case of the lock file I would expect a new lock file to be created (similar to npm, for example).

In the second case, the error happens inside create_pipfile, so maybe it is trying to create the pipflle, but still fails. So maybe it’s an another issue?

I am running into a similar problem when trying to import from a requirements file; it seems that because the Pipfile.lock is out of date it tries to remove it and fails.

PIPENV_VENV_IN_PROJECT=true pipenv install --three -r path/to/requirements.txt

Yields:

Pipfile.lock (948a23) out of date, updating to (799c69)…
Locking [dev-packages] dependencies…

This only seems to be a problem if the virtualenv is on. Thanks for the hard work maintaining this package!

I would expect such behavior from a high-level beginner-friendly software 😃

Yes, software has bugs in it. This one is maintained by usually 1-2 volunteers at most. Please try to keep the conversation productive.

When you remove pipfile.lock, what fails? You removed your lockfile and then ran what command specifically? It’s not clear what happened here from the snipped output
