Why isn't autotest working?

I\'m trying to use autotest for Rails development. It\'s supposed to run my tests automatically. Here\'s my setup:

I'm trying to use autotest for Rails development. It's supposed to run my tests automatically.

Here's my setup:

$ which ruby
/usr/bin/ruby

$ ruby -v
ruby 1.8.7 (2009-06-12 patchlevel 174) [universal-darwin10.0]

$ rails -v
Rails 2.3.9

autotest-rails (4.1.0)
ZenTest (4.4.0)

$ echo $PATH
/opt/local/bin:/opt/local/sbin:/Library/Frameworks/Python.framework/Versions/Current/bin:/usr/local/bin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/mysql/bin:/Users/ethan/bin:/opt/local/bin:/usr/local/pgsql/bin:/usr/local/git/bin:/usr/local/oracle/instantclient_10_2

Here's the gem environment:

Here's the error. It looks like autotest is trying to use some other version of Ruby.

I see two things:

Your which ruby says the default is /usr/bin/ruby, but your Autotest is calling /usr/local/bin/ruby.

sh: /usr/local/bin/unit_diff: /usr/local/bin/ruby: bad interpreter: No such file or directory

Also, your path is not organized well because you have duplicated entries. I split it on ':' then sorted it to look for duplicates:

/bin
/Library/Frameworks/Python.framework/Versions/Current/bin
/opt/local/bin # <--
/opt/local/bin # <--
/opt/local/sbin
/sbin
/Users/ethan/bin
/usr/bin
/usr/local/bin # <--
/usr/local/bin # <--
/usr/local/git/bin
/usr/local/mysql/bin
/usr/local/oracle/instantclient_10_2
/usr/local/pgsql/bin
/usr/sbin

Notice that you have duplicated /opt/local/bin and /usr/local/bin directories. Those should appear ahead of the default /usr/bin directory in order for your "personally" installed apps to be located first, so you should do some housekeeping. Once you have done that close your terminal session(s). Open a new session and try rerunning your test and see if anything has changed/improved.

The path organization is part of the problem and explains why which ruby points to the system Ruby. I suspect another part of this puzzle is that you are using #!/usr/local/bin/ruby as the "bang slash" in your scripts, or explicitly pointing to that Ruby when you call things on the command-line. That will confuse tests no end. In my scripts I use this to invoke Ruby:

#!/usr/bin/env ruby

which works nicely because it uses whatever Ruby is defined first in my path, and with this next part...

I'm a big proponent for using RVM to manage Ruby installations on Mac OS and Linux. It makes it so you don't have to install anything in your default /usr/bin ruby or even bother with adding one in /usr/local/bin. RVM puts everything in ~/.rvm and makes it really easy to install/manage/remove Ruby versions along with their associated gems, or even blow it all away by deleting that directory. Installing RVM and Gemsets are good starting places if you want to give it a try.


Rails support seems out of the ZenTest core. Install autotest-rails or downgrade to ZenTest 4.0.0 to have it working again.


I had to do the following to get my autotest working after getting the following error with ruby ree-1.8.7 + rbenv: "rbenv: autotest: command not found" even though gem said autotest was installed. The binary in /usr/local/rbenv/versions/ree-1.8.7-2012.02/bin/autotest was missing however, even after repeated reinstalls of autotest.

#> gem uninstall ZenTest #all versions
#> gem uninstall autotest autotest-fsevent autotest-growl autotest-rails
#> bundle install

My Gemfile:

group :test,:development do
  gem 'factory_girl_rails', '1.0'
  gem 'mocha','~> 0.12.1', :require => false #for mocking data
  gem 'ZenTest', '4.8.2' #DON'T USE 4.8.3 with Rails 3.2!
  gem 'autotest', '~> 4.4.6'
  gem 'autotest-fsevent','~> 0.2.8'
  gem 'autotest-rails', '~> 4.1.2'
  gem 'autotest-growl', '~> 0.2.16'
end
