Continuing on from my last post. Not an error this time, just linux specific instructions not given in Michael Hartl’s Ruby on Rails Tutorial.

So to use Autotest you need the following commands:

$ sudo apt-get install libnotify-bin

$ gem install autotest-notification

$ an-install

Done. If you would like to change the icons used they can be found at:

~/.rvm/gems/ruby-<your rails version>@<your project>/gems/autotest-notification-2.2.1/images

For example:

~/.rvm/gems/ruby-1.9.2-p0@rails3tutorial/gems/autotest-notification-2.2.1/images

Thanks to Fred Schoeneman for the handy hints on his blog.
