我在 OS X Mountail Lion v10.8.3 上通过 RVM 安装了 ruby 1.9.3-p392。我曾经$ rails new tryrails在名为 'tryrails' 的目录 'rails_projects' 中建立一个 rails 项目。但是，当我尝试$ rails server在 tryrails 中使用时，我得到了这个：
/Users/kevinrankine/.rvm/gems/ruby-1.9.3-p392/gems/sqlite3-1.3.7/lib/sqlite3.rb:6:in `require': dlopen(/Users/kevinrankine/.rvm/gems/ruby-1.9.3-p392/gems/sqlite3-1.3.7/lib/sqlite3/sqlite3_native.bundle, 9): Library not loaded: /Users/kevinrankine/.rvm/opt/sqlite/lib/libsqlite3.0.8.6.dylib (LoadError)

Gemfile 看起来像这样：
source 'https://rubygems.org'
gem 'rails', '3.2.13'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'sqlite3'
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', :platforms => :ruby
gem 'uglifier', '>= 1.0.3'
end
gem 'jquery-rails'
# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'
# To use Jbuilder templates for JSON
# gem 'jbuilder'
# Use unicorn as the app server
# gem 'unicorn'
# Deploy with Capistrano
# gem 'capistrano'
# To use debugger
# gem 'debugger'
