问题描述
我正在关注 http://ruby 上的演示应用教程.railstutorial.org/chapters/a-demo-app#sec:planning_the_application.为用户生成脚手架后.当我尝试访问 localhost:3000/users 时.我在 ExecJS 上遇到以下错误
I'm following demo app tutorial on http://ruby.railstutorial.org/chapters/a-demo-app#sec:planning_the_application. After generate scaffold for users. when i try to access localhost:3000/users. I got the following error on ExecJS

4: <title>DemoApp</title>
5: <%= stylesheet_link_tag "application", :media => "all" %>
6: <%= javascript_include_tag "application" %>
7: <%= csrf_meta_tags %>

如果我取出#line 6 <%= javascript_include_tag "application"%> 页面呈现我正在运行 ruby 1.9.3、rails 3.2.7、osx 10.5.8
The page renders if I take out #line 6 <%= javascript_include_tag "application"%>I'm running ruby 1.9.3, rails 3.2.7, osx 10.5.8
推荐答案
就我而言 这是解决办法:我刚刚修改了 gemfile，将 coffee-script-source 降级到 1.8.0，瞧！这是我的 gemfile:
In my case this was the solution:I just modified gemfile downgrading coffee-script-source to 1.8.0, and voila! Here is my gemfile:
# Use CoffeeScript for .coffee assets and views
gem 'coffee-rails', '~> 4.1.0'
# Downgrade coffee-script source
gem 'coffee-script-source', '~>1.8.0'
# See https://github.com/rails/execjs#readme for more supported runtimes
# gem 'therubyracer', platforms: :ruby
# Use jquery as the JavaScript library
gem 'jquery-rails'
