Server won't start - broken dependency on listen / rb-inotifier gems

[MaxPleaner]

I'm not sure how specific this problem is to my computer, but I figured I'd document it here anyway.

To start out with, I am running Ubuntu 14.04 and Ruby 2.2.0.

I've been trying to run volt server on an empty application and got the following error (which exited the process)

Stop Child Error: #<ArgumentError: Listen::Listener can't change state from 'backend_started' to
 'stopped', only to: frontend_ready>
/home/max/.rbenv/versions/2.2.0/lib/ruby/gems/2.2.0/gems/listen-3.0.6/lib/listen/adapter/linux.rb:31:in
 `_configure': uninitialized constant INotify (NameError)
    from /home/max/.rbenv/versions/2.2.0/lib/ruby/gems/2.2.0/gems/listen-
3.0.6/lib/listen/adapter/base.rb:45:in `block in configure'

I ran gem install rb-inotify and then, in IRB, require 'rb-notify' and INotify. I got the same uninitialized constant error.

I found rb-inotify issue about how version 0.9.7 can't be downloaded from RubyGems (this is the latest version of the gem). There's also a related RubyGems issue.

The fix?

What worked for me was to simply uninstall rb-inotifier and reinstall it.

I'm not really sure how Volt could be patched to fix this error. It's a kind of confounding error and since it prevents volt server all together, I'm worried it could be offputting to beginners to debug this.

Perhaps a dependency for a different version of the rb-inotify gem could be included in the Gemfile. Or maybe the version of listen should be changed (because rb-inotify) is called from listen.

This should be fixed. Can you check?
