Error on Ubuntu 13.04

[tobinbradley]

I'm getting an error when guard starts on Ubuntu 13.04. Other than running guard I'm a total ruby noob and I have no idea what to do. I didn't get any error messages during installation of ruby or any of the gems, and ruby --version yields ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]. After the error message guard doesn't watch/update sass, but livereload and concat seem to be working fine. My only guards being loaded are guard-sass, guard-concat, and guard-livereload. It did work fine on 12.10, and I don't think any Ruby libraries changed versions (it was Ruby 1.9.3 on 12.10 as well).

Here's the guard error message. Any help would be greatly appreciated!

Did some more debugging (if you can call it that with my Ruby skills), and I have it fixed good enough for me. I'll leave it open here because it isn't quite working like it was in case anybody wants to dig into it more.

The :all_on_start option was causing the error. Here was the original line, which causes the error:

guard 'sass', :input => 'assets/sass', :output => 'public/css', :line_numbers => true, :all_on_start => true

And taking out :all_on_start => true made the error go away and everything seems to work again:

guard 'sass', :input => 'assets/sass', :output => 'public/css', :line_numbers => true

Here's the whole original Guardfile (with all_on_start still there):

# sass to css
guard 'sass', :input => 'assets/sass', :output => 'public/css', :line_numbers => true, :all_on_start => true

# This will concatenate the javascript files specified in :files to js/main.js
guard :concat, type: "js", files: %w(vendor/bootstrap/bootstrap-tooltip vendor/bootstrap/bootstrap-modal vendor/bootstrap/bootstrap-transition vendor/bootstrap/bootstrap-button vendor/bootstrap/bootstrap-popover vendor/bootstrap/bootstrap-alert vendor/jquery-ui-1.10.0.custom.min plugins map page), input_dir: "assets/scripts", output: "public/js/main"

# live reload
guard 'livereload' do
  watch(%r{public/js/.+\.(js)$})
  watch(%r{public/css/.+\.(css)})
  watch(%r{public/.+\.(html)$})
end

It doesn't preprocess SASS on start now of course, but I can live with that. It worked fine on 12.10, so there was probably a library change in 13.04 somewhere.

Thanks so much for guard-sass, it's awesome!

Great, I'm glad you've found a fix for it. I will look into the cause when I get time.

Bit more for debugging purposes.

# sass to css
guard 'sass', :input => 'assets/sass', :output => 'public/css', :line_numbers => true, :all_on_start => true

# live reload
guard 'livereload' do
  watch(%r{public/js/.+\.(js)$})
  watch(%r{public/css/.+\.(css)})
  watch(%r{public/.+\.(html)$})
end

Kaboom.

# sass to css
guard 'sass', :input => 'assets/sass', :output => 'public/css', :line_numbers => true, :all_on_start => true

# live reload
guard 'livereload' do
  watch(%r{public/js/.+\.(js)$})
  #watch(%r{public/css/.+\.(css)})
  watch(%r{public/.+\.(html)$})
end

No errors (but Livereload isn't watching CSS).

# sass to css
guard 'sass', :input => 'assets/sass', :output => 'public/css', :line_numbers => true

# live reload
guard 'livereload' do
  watch(%r{public/js/.+\.(js)$})
  watch(%r{public/css/.+\.(css)})
  watch(%r{public/.+\.(html)$})
end

No errors, but doesn't preprocess SASS on start (I can live with that).

It looks like guard-livereload and guard-sass are head-butting there somehow. Beats me though - I haven't even done a Ruby hello world :).

Hi, I think I may have fixed the issue in the course of fixing #45. If you have time could you test out guard-sass version 1.1.0 (it's on rubygems) with :all_on_start => true and report back. Thanks.

[tobinbradley]

Fixed! Thanks for the help. Guard-sass is awesome!
