Rails:Bootstrap下拉菜单不起作用

Dav*_*nFL 1 ruby-on-rails twitter-bootstrap drop-down-menu

我是Rails的新手,并且一直在关注Michael Hartl的教程.一切都进展顺利,直到我到达下拉菜单,这是不工作,然后工作,现在不工作:(我已经阅读了几个帖子和修复,我怀疑我的修修补补已经到了非常简单,我已经做了一些事情来阻止它工作.我会说我最初在我的gem文件中有bootstrap-sass 2.x,然后将其更改为3.x,但又回到了2.x.因为我没有意识到由于类名更改而导致3.x会导致问题.所以,也许这个工作的时间是我安装了bootstrap-sass 3.x时,不确定.从我所知道的虽然一切都按照它需要的方式设置.我在Windows 8.1下开发,我不得不修复execjs和特定的runtimes.rb文件的问题.所以,这里有我的详细信息:

的Gemfile:

source 'https://rubygems.org'
ruby '1.9.3'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.0.2'
gem 'bootstrap-sass', '2.3.2.0'
gem 'sprockets', '2.11.0'
gem 'bcrypt-ruby', '3.1.2'

# Use sqlite3 as the database for Active Record
gem 'mysql2', '0.3.15'

# Use SCSS for stylesheets
gem 'sass-rails', '4.0.1'

# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '1.3.0'

# Use CoffeeScript for .js.coffee assets and views
gem 'coffee-rails', '4.0.1'

# 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', '1.2'

我将app/assets/javascripts/application.js中的指令顺序更改为:
//= require jquery //= require jquery_ujs //= require bootstrap //= require_tree .

像魅力一样工作:)
