I have been working on this feature since early november, and it has spanned 3 libraries and several months of breaking changes. Note that this is a duplicate of #3148 and #3576 -- and is resolved by #3298 which will be merged tonight

Thanks for the report and sorry for the trouble!

[glinskyc]

I installed the current master branch to use this feature, i.e. installing a package that has a VCS dependency in setup.py install_requires, but it does not appear to work.

To clarify, upon installing said package, the resulting Pipfile.lock does not contain the VCS dependency and its sub-dependencies, despite that they do get installed in the current environment. This also means if I run pipenv lock -r > requirements.txt, the VCS dependency and its sub-dependencies are not being included, but I would expect them to be.

Maybe this is already known and I am too early in trying, but I wanted to relay my attempt regardless. Any idea when we can expect the next release, which I presume will include this feature?
