rails EXECJS运行时错误 [英] rails EXECJS runtime error

问题描述

你好，我在Demo＃index中得到一个ExecJS :: RuntimeError

下面是突出显示的第6行，下面是我的完整跟踪。有人可以A：指出我正确的方向来调试这个以及一个很好的参考调试轨。我是新来的铁轨。我的猜测是我错过了一个宝石（我检查，以确保turbolinks在那里）或turbolinks中的东西是错误的。

以下也是我的gemfile

我使用Rails 4使用Rails安装程序（更新了Gems和Rails以及捆绑安装等）。

第6行高亮显示：

 <％= javascript_include_tagapplication，data-turbolinks-跟踪=> true％>

3. 在文件中保存更改


4. 在终端上执行安装包

Hello I am getting a ExecJS::RuntimeError in Demo#index

Below is the line 6 that was highlighted and below that is my full trace. Can someone either A: point me in the right direction to debug this as well as a good reference for debugging rails. I am new to rails. My guess is i'm missing a gem (i checked to make sure turbolinks was there) or something in turbolinks is wrong. I'm using Rails 4 using rails installer (after updating gems and rails and bundle install etc.).

Below is also my gemfile

Line 6 is highlighted:

<%= javascript_include_tag "application", "data-turbolinks-track" => true %>
