Question

I am trying to run some basic tests in my rails app following the edgeguides.

My rails app is working fine, it’s only when trying to run the tests.

When running a test, I get:

.../config/boot.rb:1:in `require': no such file to load -- rubygems (LoadError)
    from /Users/olivier_ntk/Sites/tennis/config/boot.rb:1
    from /Users/olivier_ntk/Sites/tennis/config/application.rb:1:in `require'
    from /Users/olivier_ntk/Sites/tennis/config/application.rb:1
    from /Users/olivier_ntk/Sites/tennis/config/environment.rb:2:in `require'
    from /Users/olivier_ntk/Sites/tennis/config/environment.rb:2
    from ./test/test_helper.rb:2:in `require'
    from ./test/test_helper.rb:2
    from test/unit/club_test.rb:1:in `require'
    from test/unit/club_test.rb:1

$ ruby -v
ruby 1.8.7 (2010-08-16 patchlevel 302) [i686-darwin10]

$ rails -v
Rails 3.0.6

$ gem -v
1.3.7

However, when I run which -a ruby, I get:

/opt/local/bin/ruby
/opt/local/bin/ruby
/opt/local/bin/ruby

I am not sure why I get 3 lines and if that is affecting calling ruby …

Answer 1

What command are you using to start the tests?
Try using “rake test” from your app’s main directory (in your case that seems to be “/Users/olivier_ntk/Sites/tennis”).

If you’re already doing that, run:

head -1 `which rake`

and reply with what ruby path you see.
