Bootstrap Rails SCSS 没有响应

Question

我刚刚进入 Rails 并且已经遇到了很大的障碍。我从一个简单的视图开始，然后导航到 / 呈现一切正常， 在桌面视图上 。

我有 Bootstrap 和 Bootswatch 运行，一切似乎都很好，直到我在 Chrome 开发工具中打开移动视口。该网站根本没有响应，但样式都在那里。

在 Chrome 开发工具中，媒体查询在我选择的任何视口中返回为 media="all"。奇怪的是，当我在移动视图上导航到 /#，然后导航到 / 时，桌面视图只是被挤压并且不符合。

我的 Gemfile:

source 'http://rubygems.org'


# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails'
# Use sqlite3 as the database for Active Record
gem 'sqlite3'
# Use SCSS for stylesheets
gem 'sass-rails'
# Use Uglifier as compressor for JavaScript assets
gem 'uglifier'
# Use CoffeeScript for .coffee assets and views
gem 'coffee-rails'
# Use Bootswatch and Bootstrap for styling
gem 'bootswatch-rails'
gem 'bootstrap-sass'
# 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'
# bundle exec rake doc:rails generates the API under doc/api.
gem 'sdoc', 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

group :development, :test do
  # Call 'byebug' anywhere in the code to stop execution and get a debugger console
  gem 'byebug'

  # Access an IRB console on exception pages or by using <%= console %> in views
  gem 'web-console'
end

# Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]

我的application.css.scss:（应该是.sass还是.scss，我都试过了）

@import "bootstrap-sprockets";

@import "bootswatch/readable/variables";

@import "bootstrap";

@import "bootswatch/readable/bootswatch";

我的application.js:

//= require jquery
//= require jquery_ujs
//= require bootstrap-sprockets
//= require turbolinks
//= require_tree .

如有任何帮助，我们将不胜感激，我已经花了整整 2 个小时试图让它工作！
