Steps to replicate

1. Install pipenv 2018.6.25
2. Create a pipfile that references a local wheel file as a requirement
3. run pipenv install

hi @KPrasch, thanks for using pipenv! I'm looking into this issue. Hold tight!

[erinxocon]

Ok @KPrasch I think I figured out the issue, the syntax to specify a wheel in a pipfile looks like this:

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

[packages]
requests = {path = "./wheelhouse/requests-2.19.1-py2.py3-none-any.whl"}

[dev-packages]

You'll notice that instead if file we have used path. Try changing it and then doing a pipenv lock!

[KPrasch]

Ah, okay! Thanks for finding this! For future reference, where can I find this documented?

[erinxocon]

I'm honestly not sure, I got the syntax from doing pipenv install ./wheelhouse/requests-2.19.1-py2.py3-none-any.whl and then looking at the generated Pipfile. If I don't find it in the docs a section may need to be created for it, feel free to make a contribution!

[KPrasch]

Ok!

For the record, something must've changed with version 2018.6.25, since we were installing .whl files using "file" as the the inline table key with prior versions of pipenv without issues; downgrading pipenv also fixes the issue.

Thanks again for your help!

[erinxocon]

I'm checking to see if this is a regression, in the meantime I have this explanation:

path is for relative paths to packages or wheels
file is for uris

[erinxocon]

I can confirm this is not a regression and was added in #540

[techalchemy]

hey @KPrasch sorry for the confusion, the file key may have worked in the prior release, but if it did it was an accident :( file is meant for URIs only -- the path key is for relative paths. That's why we have two separate keys

If this was possible in the last release I expect we're going to hear more about it so we're going to have to be prepared for this a bit more in the coming days. Sorry for the confusion and thanks for filing this issue!

[KPrasch]

Thanks for the quick responses and all your great work! :-)
