Ruby on rails Active Admin-Ruby on Rails的类型错误

我是RubyonRails（4.1.8）的新手，使用Windows8操作系统，我在gemfile中添加了GemActiveAdmin并运行了命令

rails g active_admin:install --skip-users
rake db:migrate
rails server

但我在运行时遇到以下异常

TypeError:对象不支持此属性或方法（在 c:/Sites/CleverChalk/app/assets/javascripts/active_admin.js.coffee）

有人能告诉我为什么会这样吗。我在网上读了几篇文章

咖啡脚本源代码

和

coffee rails

但它们对我不起作用

我的档案如下：

source 'https://rubygems.org'


# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.1.8'
# Use sqlite3 as the database for Active Record
#gem 'sqlite3'
gem 'pg'
gem 'activeadmin', github: 'activeadmin'
gem 'coffee-script-source', '1.8.0'
gem 'coffee-rails', '~> 4.0.0'
# Use SCSS for stylesheets
gem 'sass-rails', '~> 4.0.3'
# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'
# 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'
# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks
gem 'turbolinks'
# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
gem 'jbuilder', '~> 2.0'
# bundle exec rake doc:rails generates the API under doc/api.
gem 'sdoc', '~> 0.4.0',          group: :doc

# Use ActiveModel has_secure_password
# gem 'bcrypt', '~> 3.1.7'

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

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

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

# Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem 'tzinfo-data', platforms: [:mingw, :mswin]

我可以通过向用户重新安装activeadmin来解决此问题，这意味着添加Desive gem，如下所示：

gem 'devise' 

到gemfile，然后

bundle install
rails generate devise:install

谢谢。

看看这篇文章的答案是否对你有帮助：你使用的是什么版本的

咖啡脚本？你能显示你的
gem文件吗？
？我将其更新为-->gem“咖啡脚本源代码”，“1.8.0”编辑了这个问题。。它现在包含gemfile，在您更新到
'coffee-script-source'，'1.8.0'
后它能工作吗？
