why line defilement rails newcomer dreamhost?

ok, i have rails app set adult dreamhost i operative while ago it's broken. i don't know lot deployment environments anything greatfully atonement ignorance. anyway, looks app crashing during line config/environment.rb:

require file.join(file.dirname(__file__), 'boot')

config/boot.rb graceful many normal, nonetheless i'll consolidate here anyway.

# don't change file!
# configure your app config/environment.rb config/environments/*.rb

rails_root = "#{file.dirname(__file__)}/.." unless defined?(rails_root)

module rails

          file.read("#{rails_root}/config/environment.rb")
