Version 0.8.26 doesn't start about volt

[ryanstout]

What os and version are you on?

Confirmed to run fine for me on ubuntu 14.04 with ruby 2.2.0 and volt 0.8.27beta3, so upgrading to the latest version of the gem may fix things @ypcatify , so if youre on Linux that could fix it. If OSX it still may help as well.

Sorry for late response, I'm using OSX Yosemite with Ruby ruby-2.1.3.

Tested with ruby 2.2.0 under OS X 10.10.2. Everything works fine.

[ypcatify]

Upgrading to Ruby 2.2.0 helped. Thank you.

Doesn't work for me, fresh ruby 2.2.1 with newly created gemset, OS X 10.10.2

$ bundle exec volt server
Volt 0.8.26
Using rack adapter
/Users/d4rky/.rvm/gems/ruby-2.2.1@volt/gems/volt-0.8.26/lib/volt/server/rack/asset_files.rb:38:in `component': Unable to find component 'rspec-builder.rb', make sure the gem is included in your Gemfile (RuntimeError)

Problem is with component_paths.rb method app_folders. It does this:

app_folders += Gem.loaded_specs.values.map(&:full_gem_path).reject { |g| g !~ /volt/ }.map { |f| f + '/app' }

This would probably be a great idea if I didn't use volt as gemset name ;) This causes, like, everything to add itself to app_folders and because opal-rspec-0.3.0.beta3/app actually exists, it adds opal-rspec-0.3.0.beta3/app/rspec-builder.rb to asset loading path which causes a crashes.

The easiest solution I can think of is:

app_folders += Gem.loaded_specs.values.reject { |g| g.name !~ /volt/ }.map(&:full_gem_path).map { |f| f + '/app' }

# or a bit nicer
app_folders += Gem.loaded_specs.values.map { |g| File.join(g.full_gem_path, 'app') if g.name =~ /volt/ }.compact

# or even nicer (because of single pass) but slightly less readable
app_folders += Gem.loaded_specs.values.reduce([]) { |paths, gem| paths << File.join(gem.full_gem_path, 'app') if gem.name =~ /volt/; paths }

If you want me to send a pull request (maybe with additional test or two?), I'll be happy to provide one after wroclove.rb :)

[ryanstout]

@d4rky-pl awesome you figured it out. I hadn't been able to duplicate this on my end and I don't think anyone put together that a volt gemset was the problem. A PR would be great. I'll be at wroclove, so see you there :-)

[jhirbour]

I ran into the same issue (OS x yosemite using rvm and ruby-2.1.5) @d4rky-pl fixe looks like a cleaner way than I did it, but the principle was the same.

[nmpennypacker]

@d4rky-pl - Good call.

[ryanstout]

I believe this is fixed in 0.9, please reopen if its not.
