Yes, Gemfile and Gemfile.lock files are present at the top level.
I can get "cf logs" output for other apps I pushed. So I think the reason
that I don't see anything from "cf logs --recent" is that there are no logs
produced at all.
Anyway, whatever the root cause it may be, I think the key point is not
the root cause itself, it is the utilities that we provide to developers to
investigate when such an error occurs. I think it is really a bad user
experience for developers when such an error occurs but they can only guess
the root cause and try the solutions, rather than find clues from logs. PHP
build pack has a BP_DEBUG environment variable that helps debugging. But it
seems Ruby build pack doesn't support it.

Are your Gemfile and Gemfile.lock files literally named Gemfile and
Gemfile.lock, and both checked present at the top level of the directory
you're pushing from, on the machine you're pushing from?

The Ruby Buildpack looks for (and requires) the presence of these to
identify a Ruby app. If you've got some other setup, you can put empty
files with the appropriate names in the top level dir.

This might not be your problem, but I've seen it cause the error you
report many times.

Ning,

What is the output of `cf buildpacks`?

Hi,

Does anyone know how to debug "BuildpackCompileFailed" issue?
When I push a ruby app:
========================
...
Done uploadingOK
Starting app happy in org funorg / space development as funcloud...
FAILEDBuildpackCompileFailed
TIP: use 'cf logs happy --recent' for more
informationPivotals-iMac:happy-root-route-app pivotal$ cf logs happy
--recent
Connected, dumping recent logs for app happy in org funorg / space
development as funcloud...
========================
But I got nothing from "cf logs happy --recent".
It is "ruby '2.2.2'" in Gemfile, and my ruby build back is
cached-1.6.11. I've also tried "bundle package --all" before I push.

Any suggestions? Doesn't ruby build pack provide any logs?

Thanks,
Ning
