Bootstrap-sass gem Javascript not Working in Rails 4

Question

when using the bootstrap-sass gem i have loaded my css files properly, however have been receiving an error when i try loading the javascript files. I have followed the procedure of loading javascript from https://github.com/twbs/bootstrap-sass however when I view my webpage on localhost

I receive the error "couldn't find file 'bootstrap'"

This is what my application.js file looks like - Any help would be much appreciated!

 // This is a manifest file that'll be compiled into application.js, which will include all the files // listed below. // // Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts, // or vendor/assets/javascripts of plugins, if any, can be referenced here using a relative path. // // It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the // compiled file. // // Read Sprockets README (https://github.com/sstephenson/sprockets#sprockets-directives) for details // about supported directives. // //= require jquery //= require jquery_ujs //= require turbolinks // Loads all Bootstrap javascripts //= require bootstrap //= require_tree . 

Answer 1

From the Rails 4 the :assets group isn't used anymore , please remove the group from Gemfile :

Rails 4.0 removed the assets group from Gemfile. You'd need to remove that line from your Gemfile when upgrading. You should also update your application file (in config/application.rb):

Bundler.require(:default, Rails.env)

I got it to work by removing gem 'bootstrap-sass', '~> 3.0.3.0' out of the assets group in gemfile! YAY

您是否bundle install并确保要从资产管道加载application.js 。
