How to install packages with a vcs dependency in their setup.py

I’m working on a project at work for which one of the dependencies cannot be published to pypi, so I have to install it with the git url. Unfortunately I can’t paste the setup.py here.

What I am trying to accomplish is to use the Pipfile/Pipfile.lock as a development environment for the tool and then deploy the tool with pip install. So I’m trying to specify all my dependencies in the setup.py and then just have the -e . line in my Pipfile. My package installs perfectly fine with pip install . and pipenv install --skip-lock. However, pipenv lock fails with the error (obviously redacted):

pipenv.exceptions.ResolutionFailure: ERROR: ERROR: Could not find a version that matches packagename@ git+https://[e-mail]/user/repo.git@v0.1.0#egg=packagename from git+https://[e-mail]/user/repo.git@v0.1.0#egg=packagename                          
No versions found    

I know it’s going to be difficult to give specific advice without more information, but I’m hoping you can give me the format and conditions that must be true (does the repo need to be tagged, etc) for pipenv to resolve this dependency the way pip does. Thanks

I have a non-pypi but public github example of this issue, with the same type of setup.py trying to use a git repo as an install_requires dependency.

I attempt to install my python library using: pipenv install -e git+https://github.com/itsayellow/mlutils.git#egg=mlutils

This has a dependency to another one of my git repo python libraries, tictoc.

pip can install mlutils fine, but pipenv fails:

[pipenv.exceptions.ResolutionFailure]:       pipenv.exceptions.ResolutionFailure: ERROR: ERROR: Could not find a version that matches tictoc@ git+https://github.com/itsayellow/tictoc@master from git+https://github.com/itsayellow/tictoc@master
[pipenv.exceptions.ResolutionFailure]:       No versions found

However, pipenv will succeed if I install tictoc first using: pipenv install -e git+https://github.com/itsayellow/tictoc.git#egg=tictoc

I can then successfully use pipenv to install mlutils that depends on tictoc: pipenv install -e git+https://github.com/itsayellow/mlutils.git#egg=mlutils

So this depends on the order. If I try to install mlutils first with pipenv, it fails. But if I install its dependency tictoc using pipenv first, then a later install of mlutils will succeed.

@itsayellow I seem to be having precisely the same issue. Could it be that it is not attempting to perform a -e installation? If I attempt to install the repo using pipenv but without the -e argument it fails for me in the same way as you are reporting. So, is there some way to tell pipenv to install some VCS dependency using the -e flag?
