Key error raised on requirements subcommand when VCS dependency is specified

[fridex]

Describe the bug

Given the following Pipfile:

[[source]]
url = "https://pypi.org/simple"
verify_ssl = true
name = "pypi"

[packages]
selinon = {git = "https://github.com/selinon/selinon"}

[dev-packages]

Running the following command:

micropipenv --verbose req --only-direct

I get the following error:

Traceback (most recent call last):
  File "/Users/fridolin.pokorny/git/fridex/selinon/demo-worker/./micropipenv.py", line 1464, in <module>
    return_code = main()

    result = {"version": pipfile_entry["version"]}
KeyError: 'version'

Expected behavior

Requirements should be generated respecting VCS dependency stated in the provided Pipfile.

Heya @fridex thanks for opening the issue, sounds like a bug to me ...

If we accept the new scope proposed in #249 (point 1), this is out of scope. (because micropipenv should parse Pipfile.lock, not attempt to resolve Pipfile to Pipfile.lock)

This corresponds to the requirements feature. In some cases, users might want to convert Pipfile to requirements style output (see also pipenv requrements command).

The reported bug affects micropipenv requirements --only-direct in which case users want only direct dependencies converted to the requirements style file - hence Pipfile has to be parsed for that.

Ah, sorry - opened another issue.

Ideally yes, if there is only one standard for defining requirements and lockfiles, this would not be needed. But I would expect it will take some time (years?) to have the lockfile standard accepted and used widely. In the meantime, micropipenv could be helpful.

Does any of you plan to propose a fix for this bug?
