ruby-on-rails - 无法运行新应用程序

Question

我已经使用本指南在我的 MacOS X 中安装了 RoR http://ryanbigg.com/2010/12/ubuntu-ruby-rvm-rails-and-you/

这是我的版本:

$ 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，所以我使用本教程搜索并修改了 Gemfile: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'

当我使用

运行应用程序时

rails server

我明白了:

=> 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

我该如何解决这个问题？

Answer 1

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'

与:

:key => '_rubyrails-app_session'

然后打开 /Users/giacomo/websrc/rubyrails-app/config/initializers/wrap_parameters.rb 并替换:

wrap_parameters format: [:json]

与:

wrap_parameters :format => [:json]
