运行 rails 应用程序时出错 - ExecJS::RuntimeError [英] Error when running rails app - ExecJS::RuntimeError
问题描述
我试过在谷歌上搜索这个，但我还没有找到我的问题的答案.
I tried googling this and I haven't found an answer yet to my problem.
我正在尝试通过 rails 运行一个简单的控制器脚本，当我到达页面时它给了我这个错误.
I am trying to run a simple controller script through rails and it is giving me this error when I reach the page.
ExecJS::RuntimeError in Say#hello
显然 Say 是控制器，hello 是方法.在页面下方，我获得了有关错误的更多信息.
Obviously Say is the controller and hello is the method. Further down the page I get more info about the error.
dyld: unknown required load command 0x80000022
(in /Users/JoeMoe/Sites/demoRails/app/assets/javascripts/say.js.coffee)
我已经检查过这个文件，除了注释的代码外，没有任何内容.这里应该有什么东西吗?
I have checked this file and there is nothing in it besides the commented code. Is there supposed to be something in here?
这是 say.js.coffee 文件中的内容
Here is whats in the say.js.coffee file
# Place all the behaviors and hooks related to the matching controller here.
# All this logic will automatically be available in application.js.
# You can use CoffeeScript in this file: http://jashkenas.github.com/coffee-script/
在页面下方，我看到我可以做一个应用程序跟踪来显示我.
Down the page some more I see I can do an Application Trace which shows me.
app/views/layouts/application.html.erb:6:in `_app_views_layouts_application_html_erb__169683399_21885150'
我也可以进行框架跟踪.顺便说一下，这将是一个很长的清单.
I can also do the framework trace as well. This is going to be a long list by the way.

推荐答案
您必须为 javascript 安装一个额外的 gem.编辑 gemfile 并添加 gem 'therubyracer'.然后你可以运行 bundle 来安装新的 gem.
