Rails - can't run autotest

Question

After my upgrade to Rails 3.1.3 and Ruby 1.9.3 (via RVM) i can't normally run autotest. I don't know what has happened, but when i print:

$ autotest

It shows strange error

But when i try:

bundle exec autotest

It works. How can i fix it?

My gemfile:

Answer 1

I solved it. I found this page: http://www.viget.com/extend/how-why-to-run-autotest-on-your-mac/ and then i printed in the Terminal:

$ gem update ZenTest
$ gem cleanup ZenTest
$ gem install autotest-fsevent

After that autotest started to work fine.

Answer 2

I had that issue as well, and to fix it I had to do what you did :

$ gem update ZenTest
$ gem cleanup ZenTest
$ gem install autotest-fsevent

But I also had to add 'autotest-growl' and 'autotest-fsevent' to my gemfile, which now looks like this:

group :development do
    gem 'sqlite3'
    gem 'rspec-rails'
    gem 'autotest'
    gem 'ZenTest'
    gem 'autotest-growl'
    gem 'autotest-fsevent'
end

Then

$ Bundle install

And now

$ autotest

works just fine :)
