Need help configuring a Redis-backed library on Ru

问题:

I'm following the configuration guidelines for installing resque. I'm met with a (LoadError). I'm using RVM 1.9.2-p180, rails 3.0.6, and POW. This is probably an issue with my load path being totally wrong. So here is some extra info:

 master ~/projects/chaggregator $ which rails
/Users/boris/.rvm/gems/ruby-1.9.2-p180/bin/rails
 master ~/projects/chaggregator $ which ruby
/Users/boris/.rvm/rubies/ruby-1.9.2-p180/bin/ruby
 master ~/projects/chaggregator $ whereis ruby
/usr/bin/ruby
 master ~/projects/chaggregator $ whereis rails
/usr/bin/rails

config/resque.yml

development: localhost:6379
test: localhost:6379
staging: 
fi: localhost:6379
production: 

initializers/resque.rb:

rails_root = ENV['RAILS_ROOT'] || File.dirname(__FILE__) + '/../..'
rails_env = ENV['RAILS_ENV'] || 'development'

resque_config = YAML.load_file(rails_root + '/config/resque.yml')
Resque.redis = resque_config[rails_env] 

Terminal:

~ $ cd projects/MyApp/
 master ~/projects/MyApp $ RAILS_ENV=production resque-web rails_root/config/initializers/resque.rb
/Users/boris/.rvm/gems/ruby-1.9.2-p180/gems/resque-1.16.1/bin/resque-web:16:in `load': no such file to load -- rails_root/config/initializers/resque.rb (LoadError)

You can't use rails_root in the command line:

 master ~/projects/MyApp $ RAILS_ENV=production resque-web rails_root/config/initializers/resque.rb

try:

RAILS_ENV=production resque-web config/initializers/resque.rb
