I dig google in autotest with notification of Rails and found out this instruction is useful (http://jetpackweb.com/blog/2009/09/01/autotest- notifications-on-ubuntu-using-lib-notify/), however while I followed up to do, the result is: /home/vlpeng/.rvm/rubies/ruby-1.9.2-p180/lib/ruby/site_ruby/1.9.1/ rubygems/custom_require.rb:36:in `require'': no such file to load -- test/unit/ui/console/testrunner (LoadError) I did made installations as below three componants: Ruby-GTK+2 / Ruby-GNOME2 / ruby-libnotify and Ruby-1.9.2-p180 / Rails 3.0.9 I tried to figure out which gem and compiler are not contained in my Ubuntu 11.04, I was confused and don''t know what else I miss. Here the completed error message and screencast, any suggestions and advice will be high appreciated. http://www.screencast.com/t/MWCJGpksNw -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
