我正在使用Ruby 2.0.0和Rails 4.2.3。引導下拉菜單在heroku上不起作用
我的引導下拉菜單在heroku上不起作用。我不知道爲什麼？ 我已經試過一切，但似乎沒有任何幫助

當我檢查我的瀏覽器的JavaScript控制檯（F12），它顯示了以下錯誤：
Error: Bootstrap's JavaScript requires jQuery application-6de83ae08cb7e1d68e66d4b193a2778e.js:9:9
GET
ReferenceError: jQuery is not defined jquery.backstretch.min.js:1:1
ReferenceError: $ is not defined
，我只是不知道如何解決這個問題。 有人可以幫助我嗎？ 由於事先
嘗試在你的application.js – beydogan
引導之前要求jquery，但沒有任何反應@beydogan –
你有沒有嘗試過：'''// = require bootstrap-sprockets'''？ – laertiades
