Question

railsにてbootstrapをgemに追加し、application.jsに
//= require jquery

を追加すると

couldn't find file 'jquery' with type 'application/javascript'

上記のエラーが表示されてしまいます。

application.js

// 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 any plugin's vendor/assets/javascripts directory 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. JavaScript code in this file should be added after the last require_* statement.
//
// Read Sprockets README (https://github.com/rails/sprockets#sprockets-directives) for details
// about supported directives.

//= require jquery
//= require bootstrap-sprockets
