Pipenv: Installing local package with `pipenv install '-e .' --dev` no longer works.

[macbeth322]

The feature described https://docs.pipenv.org/basics.html#editable-dependencies-e-g-e was broken in this commit https://github.com/kennethreitz/pipenv/commit/0a48fa090e2535041e5280511a6a2f1696de6797

In the most recent version of pipenv (8.3.1), pipenv install '-e .' --dev fails with a TypeError from this line https://github.com/kennethreitz/pipenv/blob/v8.3.1/pipenv/utils.py#L540

Since '.' is a directory and not a regular file, it fails the check on L539 os.path.isfile(req.path) and the Requirements object name is None when parsing this type of requirement which causes the exception to be raised.

Installing pipenv==8.2.7 resolved this issue for me.

@grets @ipmb thanks for the report. We are aware of this issue and have a fix coming. I'm going to go ahead and close this as a duplicate of #960 #939 #949 #914 #817 with a fix pending in #958:

  ◰³ tempenv-0fe31406509ec  ~/g/test-pipenv-dep   master +  pipenv install '-e .'
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.

ah, just ran into this as well

[AlJohri]

quick workaround - add "cjSj384E" = {path = ".", editable = true} to your Pipfile manually where cjSj384E is the hash of path to the current directory. you can get this hash from checking the currently virtualenv name pipenv --venv

[techalchemy]

@AlJohri that's a nice workaround actually!

This is resolved in #958
