Guard rspec doesn't run specs - ruby-on-rails

Question

When spec or model changed, guard with options spring rspec shows next output:
04:54:44 - INFO - Running: spec/models/identity_spec.rb
Version: 1.1.2
Usage: spring COMMAND [ARGS]
Commands for spring itself:
binstub Generate spring based binstubs. Use --all to generate a binstub for all known commands.
help Print available commands.
status Show current status.
stop Stop all spring processes for this project.
Commands for your application:
rails Run a rails command. The following sub commands will use spring: console, runner, generate, destroy.
rake Runs the rake command
Frame number: 0/0
I'm using ruby '2.1.0' and 'rails', '4.1.0.rc1' with spring. So, it looks like it doesn't run anything. I tried different cmd options.
guard :rspec 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$}) { |m| "spec/#{m[1]}_spec.rb" }
watch(%r{^app/controllers/(.+)_(controller)\.rb$}) { |m| ["spec/routing/#{m[1]}_routing_spec.rb", "spec/#{m[2]}s/#{m[1]}_#{m[2]}_spec.rb", "spec/acceptance/#{m[1]}_spec.rb"] }
watch(%r{^spec/support/(.+)\.rb$}) { "spec" }
watch('config/routes.rb') { "spec/routing" }
watch('app/controllers/application_controller.rb') { "spec/controllers" }
end
This throws en error:
05:04:08 - INFO - Running: spec/models/identity_spec.rb
05:04:08 - ERROR - Guard::RSpec failed to achieve its <run_on_modifications>, exception was:

Full content there with spec helper
I've tried all different variations of options rspec, spring rspec spec and other possible including without any, but had the same result.
rspec spec without guard works fine.
I found similar problem, but it works without spring.

Answer 1

try using
guard 'rspec', :cli => '--drb' do
#your code
end
once I wrote this quick guild for my reference, see if that works for you

Answer 2

Found the problem. In guard-rspec/guard-rspec.gemspec from 4.2.2 version, line:
s.add_dependency 'rspec', '>= 2.14', '< 4.0'
Conflicted with beta version i guess. So i changed it on next:
s.add_dependency 'rspec', '>= 2.14', '~> 3.0.0.beta2', '< 4.0'
And it works!
And by the way, option spring in cmd caused test to do nothing. So, works this:
guard :rspec, cmd: 'rspec -f doc --color --require spec_helper ' do
And just guard :rspec do, and it consider options from .rspec file, in which i wasn't sure.
