Could not load 'guard/spork' or find class Guard::Spork

[Shauna]

I've been working my way through Michael Hartl's tutorial : http://ruby.railstutorial.org/chapters/static-pages?version=3.2#sec:spork.

I'm on a Windows 7 system, so I know I can't use guard-spork. But I could swear that before I was able to start a Ruby DRb server and then run 'guard' without any problems. Now I can start up a Ruby DRb server fine and it does process my RSpec tests. But when I then try to 'bundle exec guard' I get:
   ERROR: Could not load 'guard/spork' or find class Guard::Spork ...
   ERROR: Invalid Guardfile, original error is:
   undefined method 'new' for nil:NilClass
   ERROR: No guards found in Guardfile, please add at least one. ...
   Guard is now watching at 'C:/Sites/rm403'
and it doesn't detect when I change a spec file.
Here is the 'C:/Sites/rm403/Guardfile:

guard 'spork', :cucumber_env => { 'RAILS_ENV' => 'test' }, :rspec_env => { 'RAILS_ENV' => 'test' } do
  watch('config/application.rb')
  watch('config/environment.rb')
  watch(%r{^config/environments/.+\.rb$})
  watch(%r{^config/initializers/.+\.rb$})
  watch('Gemfile')
  watch('Gemfile.lock')
  watch('spec/spec_helper.rb') { :rspec }
  watch('test/test_helper.rb') { :test_unit }
  watch(%r{features/support/}) { :cucumber }
  watch('spec/support/')
end

guard 'rspec', :version => 2, :all_after_pass => false, :cli => '--drb --color' do
  watch(%r{^spec/.+_spec\.rb$})
  watch(%r{^lib/(.+)\.rb$})     { |m| "spec/lib/#{m[1]}_spec.rb" }
  watch('spec/spec_helper.rb')  { "spec" }

  # Rails example
  watch(%r{^app/(.+)\.rb$})                           { |m| "spec/#{m[1]}_spec.rb" }
  watch(%r{^app/(.*)(\.erb|\.haml)$})                 { |m| "spec/#{m[1]}#{m[2]}_spec.rb" }
  watch(%r{^app/controllers/(.+)_(controller)\.rb$})  { |m|
        ["spec/routing/#{m[1]}_routing_spec.rb",
         "spec/#{m[2]}s/#{m[1]}_#{m[2]}_spec.rb",
         "spec/acceptance/#{m[1]}_spec.rb",
         "spec/requests/#{m[1]}_spec.rb"] }
#       (m[1][/_pages/] ? "spec/requests/#{m[1]}_spec.rb" :
#                           "spec/requests/#{m[1].singularize}_pages_spec.rb")]
  watch(%r{^spec/support/(.+)\.rb$})                  { "spec" }
  watch('config/routes.rb')                           { "spec/routing" }
  watch('app/controllers/application_controller.rb')  { "spec/controllers" }
  # Capybara request specs
  watch(%r{^app/views/(.+)/.*\.(erb|haml)$})          { |m| "spec/requests/#{m[1]}_spec.rb" }
end

So is there some syntax error in my Guardfile that's preventing guard from interpreting it correctly? I tried remming out the whole spork section but then spork doesn't work at all. Can someone point me in the right direction? Thanks.

[Thibaud Guillaume-Gentil]

Can you give your Gemfile? It seems that guard-spork is missing.

[Shauna Haines]

Maybe my original post wasn't explicit enough: the guard-spork gem
won't load on Windows 7, so it is not in my Gemfile.

But I remember being able to start them separately before - first
spork and then guard.

I am using windows 7 home premium.  I successfully followed through chapter 3.

[Shauna Haines]

I see the tutorial has been updated again to use gem 'rails', '3.2.8',
and that the guard and spork related gems also have slightly different
version numbers than when I first tried it back in May. Maybe that
fixes it.

Nope, it still doesn't work for me!

I'm up to the end of Chapter 8 now but I went to the end of Chapter 3
and updated my Gemfile and Guardfile with respect to guard and spork.
So in my Gemfile under both :development and :test I tried:
gem 'rspec-rails', '2.11.0'
gem 'guard-rspec', '0.5.5'
gem 'guard-spork', '0.3.2'
gem 'spork', '0.9.0'

'bundle install' works but 'bundle exec guard' gets:
ERROR: <-[0mCould not load 'guard/spork-rails' or find class
Guard::SporkRails... but then it started "watching" anyway, followed
by a [Listen warning]: Missing dependency 'wdm' (version '~> 0.0.3')!
Please add [it] to your Gemfile...

My old Gemfile had the line gem 'spork-rails' commented out (and it
doesn't appear in the tutorial's Gemfile either), but I uncommented it
and then 'bundle install' got: Bundler could not find compatible
versions for gem "spork": In Gemfile: spork-rails ()=0 x86-mingw32
depends on spork ()=1.0rc0 x86-mingw32

By the way, I am deleting the Gemfile.lock file each time I rerun
'bundle install'.

So I tried changing gem 'spork', '0.9.0' to just gem 'spork'. Now
'bundle install' works, but 'bundle exec guard' gets the same "Could
not load 'guard/spork-rails'..." error message, watching, and 'wdm'
warning as before.

I changed a line in one of my /spec/requests files, but there was no
response from guard.

Can you check your Gemfile for me and list the versions you have of
all the guard- and spork- related gems? Is 'spork-rails' in there?

Thanks!

By the way, I am on a 64-bit machine.

Please try with guard-spork 1.2.0 it should work on Windows now.

I changed my Gemfile similar to yours (listed below), restarted my
computer, deleted the Gemfile.lock file, ran 'bundle install' (no
problems with that), and ran 'bundle exec guard'. I got the same
messages as before:

ERROR: <-[0mCould not load 'guard/spork-rails' or find class
Guard::SporkRails

ERROR: <-[0mcannot load such file -- guard/spork-rails
ERROR: <-[0mInvalid Guardfile, original error is:

ERROR: <-[0mNo guards found in Guardfile, please add at least one.
...
<-[0mGuard is now watching at...

Then I changed a spec file, and there was no response from guard.
Then I started 'bundle exec spork' in another "Command Prompt with
Ruby and Rails" window, and changed the spec file again. There was
still no response.

Sorry, Thibaud, I missed your email earlier. But I just now tried
changing my version to guard-spork 1.2.0 and that made no difference
in my results.

Hi,

First thing, guard-spork-rails doesn't exist : http://rubygems.org/gems/guard-spork-rails so you should remove it from your Guardfile (that's the cause of the "Could not load 'guard/spork-rails' or find class Guard::SporkRails" issue you're having);

Secondly, in your Guardfile you should move the "guard 'spork'" block before the "guard 'rspec'" block.

I hope that helps,

Regards.

Rémy

[Shauna Haines]

Yes, Rï¿œmy, thank you, thank you! Moving the "guard 'spork'" block
from before to after the "guard 'rspec'" block did the trick!

By the way, I don't have a gem called 'guard-spork-rails' in my
Gemfile. It's a mystery to me where the wording of that "Could not
load 'guard/spork-rails' or find class Guard::SporkRails" message was
coming from. But moving the guard 'spork' block to the bottom of the
Guardfile made it go away, as well as activating guard to watch for my
rspec tests.

You're welcome Shauna!! Just a quick note, you have to put the "guard 'spork'" *at the top* of your Guardfile (at least before the "guard 'rspec'" block), not at the bottom (as you said in your previous reply).

Regarding "guard-spork-rails", that's the point actually, since you had "guard 'spork-rails', :rspec_env => { 'RAILS_ENV' => 'test' } do" in your Guardfile, Guard tried to search for a guard/spork-rails file or a Guard::SporkRails class but since it wasn't in your Gemfile (obviously since the gem doesn't exist at all!) an error was thrown.

I hope that clarifies a bit how Guard works, I encourage you to read its source code, it's not that complex! ;)

Rémy
