Guardfile

guard :teaspoon, cmd: 'spring teaspoon', environment: 'spec/teaspoon_env.rb' do
  # Implementation files
  watch(%r{app/assets/javascripts/(.+).coffee}) { |m| "#{m[1]}_spec" }

  # Specs / Helpers
  watch(%r{spec/javascripts/(.*)})
end

Also, if I run teaspoon directly, it works without any error.

@achrome I had exactly the same problem with almost the same environment setup as yourself. A series of comments on a teaspoon issue helped me fix this: jejacks0n/teaspoon#197. Specifically changing this line of code in development.rb fixed this issue for me.

config.assets.raise_runtime_errors = false

Hope this points you in the right direction.

Have the same error over here. Changing that line in development.rb didn't help.
