What is this error?

I seem to have correct include path, but a lot of gems can't be loaded via "required". What could be the problem?

#!/usr/bin/ruby -w require "cgi" # cant load this require "actionpack" # can not load this

# /var/www/ruby/test.rb /var/www/ruby/test.rb:3:in `require': no such file to load -- /var/lib/gems/1.9.2/gems/passenger-3.0.11/test/stub/vendor_rails/minimal/actionpack (LoadError)         from /var/www/ruby/test.rb:3:in `<main>'

First.. paste in your file:   require 'rubygems' before another require's:

Hi Alex,

I tried you suggestion. Still getting the same error.

#!/usr/bin/ruby1.9.2 #!/opt/framework3/ruby/bin/ruby -w #!/usr/bin/ruby -w require 'rubygems' require "cgi" require "action_pack"

./test.rb:6:in `require': no such file to load -- action_pack (LoadError)         from ./test.rb:6:in `<main>'

What does gem list show?

Here is the o/p of gem list

Heh… seems you have problem with RVM load?

As your RVM installed in systemwide maner

check that your $HOME/.bashrc file have this line at the end: source ‘/usr/local/rvm/scripts/rvm’

If not then add and reload terminal. Then…

  1. Navigate to folder with your script and type that: rvm --create --rvmrc 1.9.3@test_sctipt
  2. Then install all needed gems
  3. And replace that: #!/usr/bin/ruby1.9.2 #!/opt/framework3/ruby/bin/​ruby -w #!/usr/bin/ruby -w with this one: #!/usr/bin/env ruby

Hi Alex, thanks a lot for some informative advice. I tried those things. Still no luck :confused:

  1. You sure that actionpack is installed?

  2. Instead of require ‘actionpack’ use:

require ‘action_pack’

Yes. actionpack is installed.....

Hi Alex, changing it to require 'action_pack' worked. But other gems has the same issue -

# ./test.rb /usr/local/rvm/rubies/ruby-1.9.3-p125/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- bundler (LoadError)         from /usr/local/rvm/rubies/ruby-1.9.3-p125/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'         from ./test.rb:8:in `<main>'

Hmm…

What gives this command? rvm current

Have you tried require commands from ruby console(irb) ?

Hi Alex,

I was able to solve the issue. Don't know what was wrong, but I removed ruby, gems, rails, rvm completely from the machine. Rebooted and installed everything freshly. That worked, now no more errors in loading any gem.

thanks for your help
