Question

I encounter identical issues with some Ruby gems in Rails application.

When I use:

require 'rubygems'
require 'uuidtools'

or

require 'rubygems'
require 'json'

in Rails application, I get the “no such file to load — uuidtools” error (or “no such file to load — json” – respectively).

• Both gems are installed properly
• When I type these directive pairs in irb, I get “true” as a result.
• When I try to run application with rails server or in a NetBeans debugging session, I get “no such file to load”
• It seems that this issue concerns many of other gems installed.

Answer 1

I added gems to Gemfile and it helped.
