为什么我的Gemfile不能运行？

Question

我下面on Rails的教程Hartl的红宝石，和上午在本教程的

当建立一个Rails应用程序，它说要运行这些命令：

cd first_app_direcory 
sublime Gemfile 
bundle update 

的sublime Gemfile命令编辑的Gemfile明显，但是当我尝试运行命令bundle update我收到以下错误：

bundle update 
Gemfile syntax error: 
ruby 2.0.0 
     ^
/home/cameron/ruby/ror/first_app/Gemfile:2: 
syntax error, unexpected tINTEGER, 
expecting '(' 
ruby 2.0.0 
     ^

我拿着这两个线条勾勒出的Gemfile的，即使它说，包括他们。另外，我尝试了Ruby 1.9.3，并且仍然收到相同的错误消息。

ruby 2.0.0 
#ruby-gemset=railstutorial_rails_4_0 

将这些线条取出后，它就起作用了。我试图让它与gemfile中的那些行一起工作。我怎样才能做到这一点？

这是一个完整的Gemfile：

source 'https://rubygems.org' 
ruby 2.0.0 
#ruby-gemset=railstutorial_rails_4_0 

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails' 
gem 'rails', '4.0.0' 

# Use sqlite3 as the database for Active Record 
group :developent do 
    gem 'sqlite3', '1.3.7' 
end 

# Use SCSS for stylesheets 
gem 'sass-rails', '4.0.0' 

# Use Uglifier as compressor for JavaScript assets 
gem 'uglifier', '2.1.1' 

# Use CoffeeScript for .js.coffee assets and views 
gem 'coffee-rails', '4.0.0' 

# See https://github.com/sstephenson/execjs#readme for more supported runtimes 
# gem 'therubyracer', platforms: :ruby 

# Use jquery as the JavaScript library 
gem 'jquery-rails', '2.2.1' 

# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks 
gem 'turbolinks', '1.1.1' 

# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder 
gem 'jbuilder', '1.0.2' 

group :doc do 
    # bundle exec rake doc:rails generates the API under doc/api. 
    gem 'sdoc', '0.3.20',require: false 
end 

# Use ActiveModel has_secure_password 
# gem 'bcrypt-ruby', '~> 3.0.0' 

# Use unicorn as the app server 
# gem 'unicorn' 

# Use Capistrano for deployment 
# gem 'capistrano', group: :development 

# Use debugger 
# gem 'debugger', group: [:development, :test] 

Answer 1

你应该有

ruby '2.0.0' 

代替

ruby 2.0.0 

在Gemfile。

Answer 2

我认为你需要引号2.0.0左右。

类似于ruby "2.0.0"。
