So I’m at a loss with this one. My error is:

Missing these required gems: jrails You’re running: ruby 1.8.7.72 at /usr/bin/ruby1.8 rubygems 1.3.6 at /home/ryann/.gem/ruby/1.8, /usr/lib/ruby/gems/1.8 Run rake gems:install to install the missing gems.

I have unpacked jrails in my vendor directory and frozen my local rails environment. Everything works fine on my local machine.

I am using config.gem ‘jrails’ in my environment.rb file.

My trace is (sorry for the mess):

Anyone got any ideas on why I’m still missing a gem when I’ve unpacked it?

    The problem is in shared hosting. There you usually have common gems repository for all users and local in your home directory for only you. The problem can be solved by specifying correct paths in your config/preinitializer.rb or config/environment.rb

    ENV['GEM_PATH'] = '/home/[username]/ruby/gems:/usr/lib/ruby/gems/1.8'
Gem.clear_paths

    This is path structure on my hosting, you may need to updated it for yours.

    edit
    Checked my sources, you may also need to add this before those lines:

    require 'rubygems'
require 'rubygems/gem_runner'
