When I try to deploy my Ruby on Rails app to Heroku I get some errors:

I use Ruby 2.4.0, Rails 5.2.3, and Bundler is 2.0.2.

Below I present full errors from heroku logs:

When I run heroku buildpacks I just see

Buildpack URL https://github.com/gunpowderlabs/buildpack-ruby-rake-deploy-tasks

UPDATED

I used: heroku buildpacks:remove https://github.com/gunpowderlabs/buildpack-ruby-rake-deploy-tasks

and after this:

git push heroku master

gives me below errors:

    Are your `Gemfile` and `Gemfile.lock` up to date, and included in your repository? – ChrisGPT was on strike Jun 29 '19 at 19:42
  • @Chris Yes, `Gemfile` and `Gemfile.lock` are included normally. – Miro Jun 29 '19 at 20:12
  • Please [edit] your question and add the log output that precedes what you've already shared. – ChrisGPT was on strike Jun 29 '19 at 20:15
  • I just edited the post and added the Heroku logs. – Miro Jun 29 '19 at 20:35

    Okay, so your log says `No web processes running`. (a) What's in your `Procfile`? (b) Are your `Gemfile` and `Gemfile.lock` checked into your repository? – ChrisGPT was on strike Jun 29 '19 at 20:46
  • (a) I don't have this file in my project or I don't know that I have it. (b) yes, they are included. – Miro Jun 29 '19 at 21:04
  • Are the `Gemfile` and `Gemfile.lock` in the root (top directory) of your repository? Is that the complete build output? There should be a whole lot more. – ChrisGPT was on strike Jun 29 '19 at 23:31
  • @Chris Yes, it's normal that this files are in the root of project. Where are they supposed to be like not in the main catalog? – Miro Jun 30 '19 at 08:33
  • No, they should be in the root. I'm just trying to figure out why your build log is so short. It doesn't appear to install any dependencies... have you manually set a buildpack, or are you relying on buildpack detection? Try running `heroku buildpacks` and see what that says. – ChrisGPT was on strike Jun 30 '19 at 13:15
  • @Chris Hmm, `heroku buildpacks` shows only `Buildpack URL` `https://github.com/gunpowderlabs/buildpack-ruby-rake-deploy-tasks` – Miro Jun 30 '19 at 14:05

Hmm, heroku buildpacks shows only

Buildpack URL https://github.com/gunpowderlabs/buildpack-ruby-rake-deploy-tasks

There's your problem. At some point you explicitly chose this buildpack, and it's the wrong one. I suggest removing the buildpack setting:

heroku buildpacks:remove https://github.com/gunpowderlabs/buildpack-ruby-rake-deploy-tasks

Then run heroku buildpacks again. You should see something like

<your-app> has no Buildpack URL set.

Once that's done, redeploy your code. Heroku will recognize a Ruby project by the presence of a Gemfile and use the appropriate buildpack automatically.

  • OK, I done your above suggestions. Everything is fine to time until bundle completed: `remote: ! Could not detect rake tasks` `remote: ! ensure you can run '$ bundle exec rake -P' against your app` `remote: ! and using the production group of your Gemfile.` `remote: ! Activating bundler (2.0.1) failed:` `remote: ! Could not find 'bundler' (= 2.0.1) - did find: [bundler-2.0.2]` `remote: ! Checked in 'GEM_PATH=vendor/bundle/ruby/2.4.0', execute 'gem env'` `remote: ! To install the version of bundler this project requires, run 'gem install bundler -v '2.0.1''` – Miro Jun 30 '19 at 15:00
  • This is very hard to read in a comment. Please edit your question and add the updated information there instead. – ChrisGPT was on strike Jun 30 '19 at 15:07
  • I see now one more thing: when I uninstall all bundler versions (2.0.1 and 2.0.2) and install 2.0.1 again as in below errors - I see that `Installing dependencies using bundler 2.0.2` when I try to `git push heroku master` again. Do you know why? – Miro Jun 30 '19 at 16:26
  • And on the bottom of Gemfile.lock is: `RUBY VERSION: ruby 2.4.0p0` and `BUNDLED WITH: 2.0.1` – Miro Jun 30 '19 at 17:05
  • OK, I solved above problem and I add the updated information. Thanks :) – Miro Jul 01 '19 at 15:01

OK, I solved the problem. Maybe it will help someone in the future:

  • update Ruby version to 2.6.1
  • gem uninstall bundler and install again gem install bundler -v 2.0.2
  • delete Gemfile.lock and bundle install
  • git push heroku master
  • it works :)
