這是我放：無法生成模式：「您已經激活multi_json 1.7.2，但你的Gemfile需要multi_json 1.4.0」
$軌生成腳手架Foobar的內容：字符串
這裏的我得到：

我正在使用Michael Hartl的Rails教程。這裏是我的Gemfile： 源「https://rubygems.org」
gem 'rails', '3.2.8'
gem 'twilio-ruby'
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 'coffee-rails', '3.2.2'
gem 'uglifier', '1.2.3'
end
gem "twitter-bootstrap-rails"
gem 'less-rails-bootstrap', '2.0.6'
gem 'jquery-rails', '2.0.2'
gem "therubyracer"
group :development, :test do
gem 'sqlite3', '1.3.5'
gem 'rspec-rails', '2.11.0'
end
gem 'annotate', '2.5.0', group: :development
group :production do
end
group :production do
gem 'pg'
end
我以前能夠生成關於這個應用程序的模型，所以我不知道在這期間發生了什麼事。無法通過搜索錯誤消息找到任何內容。感謝您的任何指導！
