Error on custom_require.rb when rspec executed

Hello all,

I’m bekkou68.
I have a error on custom_require.rb, which occurred when I execute

I executed the following command.
$ script/spec spec/models/

Then, I got the following result.

Should I add ‘require xxx’ ?
Are they some wrong codes on custom_require.rb?
Should I update RubyGems?

I’m really happy if you help me.


The error is a couple steps back up the trace, in rspec’s rails.rb.
The problem is that you’re running an old version of rspec_on_rails,
which expects ApplicationController to be defined in app/controllers/
application.rb, which it isn’t anymore. Upgrading to the new version
of rspec_on_rails will fix this.

Dear Mr.Matt,

Thanks for your message, and I’m sorry that I reply late.

Upgrading to the new version of rspec_on_rails will fix this.
I tried to update rspec with the following command.
$ ruby script/plugin install git:// -r
‘refs/tags/1.2.7’ --force
$ ruby script/plugin install git://
-r ‘refs/tags/’ --force
$ ruby script/generate rspec

Then I can’t execute spec,
$ script/spec -v

script/spec:3:in `require’: no such file to load – spec (LoadError)

from script/spec:3

The contents of spec is following,
$ more spec

#!/usr/bin/env ruby

$LOAD_PATH.unshift(File.expand_path(File.dirname(FILE) + "/…/


require ‘spec’

Now I can’t solve this problem.
I’m happy when you help me.


rspec-rails is surely working for me.
Your script/spec file seems like broken, though, I think you’d better
recreate your whole project and try again from scratch.
I recommend you not to edit the generated script/spec file unless
you’re writing a patch for the RSpec project to fix a bug within

If you’re not sticking on vendorizing plugins, config.gem feature
might be an easier way for you.
Put the following lines in your config/environments/test.rb file:

config.gem ‘rspec’, :lib => false, :version => ‘1.2.8’
config.gem ‘rspec-rails’, :lib => false, :version => ‘’

and run:

% ruby script/generate rspec
