pipenv-pex's Issues

KeyError: 'version' when package is installed in editable mode

pipenv-pex fails with KeyError: 'version' when a package is installed in editable mode (pipenv install -e) because there is no version specified in the lockfile.

To reproduce:

$ putup myproject
$ cd myproject
[add a myproject:main entry point]
$ pipenv install -e .
$ pipenv install --dev pipenv-pex
$ pipenv run pipenv-pex --entry-point myproject:main
Traceback (most recent call last):

KeyError: 'version'

The default section of Pipfile.lock looks like this (with no version for myproject):

    "default": {
        "myproject": {
            "editable": true,
            "path": "."
        },
        "pyscaffold": {
            "hashes": [
                "sha256:862ba8415361c7b9947bc9aba83c12af325e61f6c1f70890759b9e9bef498ab7",
                "sha256:96c3e7f5529df0b5b351e879a141e1e5c9f26211f30d493c23d8c09d9d610a6f"
            ],
            "markers": "python_version >= '3.4'",
            "version": "==3.2.3"
        }
    },

Pipfile information relevant to PEX files

• pypi index URL
  pex flag --index-url
  pipfile field https://pipenv.readthedocs.io/en/latest/advanced/#specifying-package-indexes
• interpreter constraint (e.g. "CPython>=2.7,<3")
  pex flag --interpreter-constraint
  pipfile field "python_version" (can only constrict version as far as I can see, not interpreter)
