Hello!  
I’m developing a ruby app, and i’m using NetBeans IDE 6.8 for  
programming, so my problem now it’s that i can execute my app without  
problems using Netbeans, but if i do ruby myapp.rb from terminal , i  
have the next message :

usr/local/lib/site\_ruby/1.8/rubygems/custom\_require.rb:31:in  
`gem_original_require': no such file to load -- ntp (LoadError) from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:31:in`require’  
from ./Init\_indoor\_unit.rb:16  
from  
/usr/local/lib/site\_ruby/1.8/rubygems/custom\_require.rb:31:in  
`gem_original_require' from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:31:in`require’  
from Main\_loop.rb:20

My problem it’s that a didn’t take care about ruby libraries used by  
Netbeans, in NetBeans i used Jruby 1.4 and for my system its Ruby 1.8…  
☹

My problem now it’s that i don’t know how migrate the libraries , or do  
something to execute my app without Netbeans…

What must i do?

Thanks!!

sudo gem install ntp

would be the place to start 🙂

Right – the gems installed for Jruby are totally separate from the  
gems used by MRI.
