我现在正在构建一个基本的RoR应用程序,但是在我的开发和生产环境中,我无法对boostrap css进行自定义,并且
javascript没有加载(但是对于我的JW Player在主页上).例如,下拉功能对导航栏不起作用,当我尝试删除文件时,“Destroy”功能不起作用.

这是我的Gemfile：

    source 'https://rubygems.org'
    ruby '2.0.0'

    # Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
    gem 'rails', '4.0.2'

    # Use SCSS for stylesheets
    gem 'sass-rails', '~> 4.0.0'

    # 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', '~> 1.2'

    gem 'bootstrap-sass'

    gem 'devise', '~> 3.1.0.rc2'

    gem 'rake', '~> 10.3.2'

    gem 'jwplayer-rails', '~> 1.0.1'

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

    group :production do
        gem 'pg'
        gem 'rails_12factor'
    end

    group :doc do
      # bundle exec rake doc:rails generates the API under doc/api.
      gem 'sdoc', require: false
    end

    # Use ActiveModel has_secure_password
    # gem 'bcrypt-ruby', '~> 3.1.2'

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

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

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

Application.js:

Application.css:

 *= require_tree .
 *= require_self

I placed these css customizations in an scss file, which are not being recognized: 

@import "bootstrap";

$navbar-margin-bottom:         0px;
$navbar-default-bg:            black;
$navbar-default-brand-color:   #ffffff;
$brand-primary:                #ff00ff;
$link-hover-color:             #00ffff;

任何人都可以提供此问题的帮助吗？我将不胜感激.正如我在标题中提到的,我正在运行ruby 1.9.3和rails 4.1.4.

最佳答案 我认为这完全是订购问题.

在你的application.js中,你需要在jquery之后需要bootstrap.

在你的scss文件中,你应该做@import“bootstrap”;设置变量后.
