Rails one-click droplet unicorn is failing to find a gem; I can't tell if the right version of the gem is installed.

My production app has been running for a while. Then yesterday I did a git pull that changed four files and my site stopped loading.

The culprit appears to be unicorn failing to run properly.

No matter what I do, unicorn endlessly crashes and respawns with the following error:

I, [2017-05-31T15:01:10.470158 #3601]  INFO -- : worker=0 spawning...
I, [2017-05-31T15:01:10.471573 #13738]  INFO -- : worker=0 spawned pid=13738
I, [2017-05-31T15:01:10.471847 #13738]  INFO -- : Refreshing Gem list
E, [2017-05-31T15:01:10.499302 #13738] ERROR -- : Could not find i18n-0.8.4 in any of the sources (Bundler::GemNotFound)
/usr/local/rvm/gems/ruby-2.4.0/gems/bundler-1.14.6/lib/bundler/spec_set.rb:87:in `block in materialize'

Yet running bundle install shows that i18n-0.8.4 is present in my installed gems list.

I’ve run down the rabbit hole trying to un/reinstall the gem. It always reports success with the correct version number.

But If I physically list the gems in my gem path, the directory is titled i18n-0.8.1.

After a successful uninstall, directory remains in place with the wrong version number. Same with after a reinstall reporting the correct number is installed.

In my attempts to flush the gemset with rvm, I’ve managed to break my rails user permissions to gem/bundle install install so that I now have to sudo to get them to run without permissions errors.

And still unicorn can’t find the right gem so my site refuses to load.

Can anyone help?

Same problem here. Have anyone found a solution to this?

Same problem and no solution


Try listing your gems:

gem query --local


ruby -e 'puts Gem::Specification.all_names'
