Editable installs that depend on each other and use flit build system do not resolve

Hi everyone,

I have a Pipfile in my project root that’s similar to this:

[packages]
mypackage = {path = "packages/mypackage", editable = true}
mypackage-cli = {path = "packages/mypackage-cli", editable = true}

mypackage-cli also depends on mypackage. However, if the version of mypackage isn’t yet on Pypi, pipenv is unable to make the lockfile. I’m hoping it would satisfy mypackage-cli’s dependency on mypackage through the mypackage editable install.

Is there a way to do this with Pipenv?

Thank you!

I modified the other example I linked to so both editable packages were in their own directory and then I pointed one of them to depend on the other via install_requires= and it in fact doesn’t work. I tried downgrading to an earlier release this year before index restricted package change and it has the same issue:

✘ Locking Failed! 

The only work around that I can think for now is to not include the install_requires in the setup.py of the other project as that is what is causing it – having two editable dependencies that depend on each other without explicitly defining it does work, but yeah seems like there is an edge case to potentially improve with this report.

Awesome! That worked. Nice work and thank you so much!
