无法运行新的应用程序

Question

我使用本指南 http://ryanbigg.com/2010/12/ubuntu-ruby-rvm-rails-and-you/

这里我的版本在我的MacOS X系统安装回报率：

$ ruby --version 
ruby 1.8.7 (2010-01-10 patchlevel 249) [universal-darwin11.0] 
$ rails --version 
Rails 3.2.3 
$ gem --version 
1.8.23 

我无法运行我的应用程序，所以我GOOGLE和修改的Gemfile使用本教程：http://ruby.railstutorial.org/ruby-on-rails-tutorial-book

现在，这是我的Gemfile：

source 'https://rubygems.org' 

gem 'rails', '3.2.3' 

# Bundle edge Rails instead: 
# gem 'rails', :git => 'git://github.com/rails/rails.git' 

group :development do 
    gem 'sqlite3', '1.3.5' 
end 

# Gems used only for assets and not required 
# in production environments by default. 
group :assets do 
    gem 'sass-rails', '3.2.4' 
    gem 'coffee-rails', '3.2.2' 

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

    gem 'uglifier', '1.2.3' 
end 

gem 'jquery-rails', '2.0.0' 

# 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 'ruby-debug19', :require => 'ruby-debug' 

当我运行使用

rails server 

我得到这个应用程序：

=> Booting WEBrick 
=> Rails 3.2.3 application starting in development on http://0.0.0.0:3000 
=> Call with -d to detach 
=> Ctrl-C to shutdown server

我怎样才能解决这个问题？

Answer 1

发生此错误是因为新的ruby有另一种散列语法。你使用的教程已过时，我建议尝试一下：http://railsapps.github.com/installing-rails.html 这是我能找到的最好的。它也不断更新。

在你的情况下，你只需要安装新版本的红宝石，然后重新安装导轨。

Answer 2

通过使用Ruby 1.9.x而不是1.8.7。

，或者打开/Users/giacomo/websrc/rubyrails-app/config/initializers/session_store.rb并替换：

key: '_rubyrails-app_session' 

有了：

:key => '_rubyrails-app_session' 

开放/Users/giacomo/websrc/rubyrails-app/config/initializers/wrap_parameters.rb和更换：

wrap_parameters format: [:json] 

有了：

wrap_parameters :format => [:json]
