我已经安装了RVM来处理我的所有rails项目。以下是环境细节：
rvm list
rvm rubies
=* ruby-1.9.3-p448 [ i686 ]
使用Ubuntu 12.04并遵循these instructions for install of RVM, ruby。
安装完导轨后，看起来一切正常：
gem install rails --version=3.2.13
Fetching: rails-3.2.13.gem (100%)
Successfully installed rails-3.2.13
Installing ri documentation for rails-3.2.13
1 gem installed
但是当我检查rails版本时，我收到以下错误
sites$ rails -v
/home/danny/.rvm/rubies/ruby-1.9.3-p448/lib/ruby/site_ruby/1.9.1/rubygems/core_ext
/kernel_require.rb:51:in
`require': cannot load such file -- /home/danny/sites/config/boot (LoadError)
from /home/danny/.rvm/rubies/ruby-1.9.3-p448/lib/ruby/site_ruby/1.9.1/rubygems
/core_ext/kernel_require.rb:51:in
`require'
from script/rails:5:in `<main>'
我曾尝试过两次重新安装rvm，ruby和rails，但没有快乐。
更新 脚本rails看起来像这样：
APP_PATH = File.expand_path('../../config/application', __FILE__)
require File.expand_path('../../config/boot', __FILE__)
require 'rails/commands'
