The labels on this github issue will be updated when the story is started.

[sclevine]

Can you provide a sample app that produces this error?

[rogeruiz]

https://github.com/18f/tock on the master branch @sclevine

[rogeruiz]

@sclevine an engineer on our team mentioned that it seems like it's breaking while it's generating the requirements.txt. cc: @Jkrzy

[sclevine]

Thanks! Prioritizing now.

[astrieanna]

@rogeruiz We're working on reproducing this issue, and have a couple questions.

• are you using only the python buildpack for this app, or multiple buildpacks?
• we noticed that tock has a requirements.txt file in the repo; is that not there when you're pushing the app?
• could you post a bit more of the output, starting from installing python?

[ameyer-pivotal]

@rogeruiz Our guess is that perhaps something is messing with your python version (such as another buildpack, if using multibuildpacks). Looking at the stack trace you posted, we found the relevant code in Pipenv. It looks like it's in the middle of trying to warn you about the python version:

https://github.com/pypa/pipenv/blob/9b5f5338277cb42382f147f92f2e5163e3a547f4/pipenv/core.py#L638

[rogeruiz]

@astrieanna

are you using only the python buildpack for this app, or multiple buildpacks?

Just the python build pack. We recently migrated from using requirements.txt and pip to pipenv.

we noticed that tock has a requirements.txt file in the repo; is that not there when you're pushing the app?

That was just added a few hours ago. But ideally, we'd like to have that not pushed up by adding it to the .cfignore as we only generate it for dependency management tooling. But it seems like we need to push it up for the build pack to be successful.

could you post a bit more of the output, starting from installing python?

Sure, here's the output.

Interesting, @ameyer-pivotal. Thanks for the link to the source. Seems like this could potentially be an issue in pipenv, right? I can go ahead and open an issue over there regarding this. Doesn't seem like it should be choking on printing out the python version.

🤔 Is it possible that these two files are conflicting in the build pack?

• https://github.com/18F/tock/blob/master/Pipfile
• https://github.com/18F/tock/blob/master/runtime.txt

Both should be pointing to python 3.6.x.

[ameyer-pivotal]

@rogeruiz Though we haven't pinned the issue to the buildpack or pipenv, filing an issue with pipenv could be useful, as I agree it should at least handle this case more gracefully.
