无法在OS X上使用rails服务器

Question

我在OS X Mountail Lion v10.8.3上通过RVM安装了ruby 1.9.3-p392。我使用$ rails new tryrails在名为'tryrails'的目录'rails_projects'中设置了一个rails项目。然而，当我尝试在tryrails使用$ rails server，我得到这个：

    from script/rails:6:in `<main>' 

的的Gemfile看起来是这样的：

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'

任何想法，我该如何解决这个问题？我真的不知道我在做什么:(

Answer 1

在我看来就像没有安装sqlite3的宝石尝试运行命令：

bundle install 

也许一个长镜头，但值得一试，如果你最近没有运行。

Answer 2

你有sqlite3的两个版本尝试运行此命令

gem cleanup

此命令将删除（卸载）所有VERS宝石的离子，最新的 除外。
