Claim a 'caplerano' / capistrano break

Question

I added this line to my deploy.rb:

require 'bundler/capistrano'

and now I get this message when I run cap -T:

/Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `gem_original_require': no such file to load -- bundler/capistrano (LoadError)
    from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `require'
    from /Library/Ruby/Gems/1.8/gems/capistrano-2.5.8/lib/capistrano/configuration/loading.rb:152:in `require'

Here is another important piece of information:

dons-macbook:Gems don$ gem which bundler
/usr/local/lib/ruby/gems/1.9.1/gems/bundler-1.0.7/lib/bundler.rb
dons-macbook:Gems don$ gem which capistrano
/usr/local/lib/ruby/gems/1.9.1/gems/capistrano-2.5.19/lib/capistrano.rb
dons-macbook:Gems don$ ruby --version
ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-darwin10.4.0]

Answer 1

The conclusion from it cap -Tsays that it works in Ruby 1.8, not 1.9 (look at the path to the stone in the output). Check it out PATH. Better yet, use RVM to manage your versions of Ruby, and you won’t get such problems.
