我创建了 Rails 应用程序，并在其中创建了一个数据库（空）。当我尝试查看我的产品页面时，我在http://localhost:3000/products页面上收到以下错误。在迁移数据库之前，该应用程序运行正常。我正在使用 therubyracer 并且在 Windows 7 上。

ExecJS::ProgramError in Products#index
Showing C:/RailsInstaller/DevKit/home/JP/nameofapp/app/views/layouts/application.html.erb where line #16 raised:

这是我在 Rails 服务器上得到的：

感谢您的任何帮助。

发生该错误是因为在查找位于 app/assets 中的正确资产时存在一些问题。要解决此问题，您可以按照以下步骤操作。

将gem 'coffee-script-source', '1.8.0'添加到 Gemfile 并运行bundle install然后运行​​bundle update coffee-script-source 重新启动 rails server 或者有一个肮脏的解决方法是从

<%= stylesheet_link_tag "application", media: "all", "data-turbolinks-track" => true %>
<%= javascript_include_tag "application", "data-turbolinks-track" => true %>
<%= csrf_meta_tags %>

至

<%= stylesheet_link_tag "default", media: "all", "data-turbolinks-track" => true %>
<%= javascript_include_tag "default", "data-turbolinks-track" => true %>
<%= csrf_meta_tags %>

但请注意，此解决方法并不能真正解决应用程序问题，它只是让您的应用程序在没有预期的样式表和 javascript 的情况下工作。

我从 application.js 中删除了 require_tree 并且它有效

//= require jquery 
//= require jquery_ujs 
//= require turbolinks 
// require_tree .

我认为最好的解决方案是删除 application.js 文件中的斜杠，例如

= require jquery
= require jquery_ujs
= require turbolinks
= require_tree .

我也遇到了这个问题，请查看此线程上的广泛解决方案， ExecJS::RuntimeError on Windows 试图遵循@Kevin P 的 ruby​​tutorial。此外，@evedoevelli 在另一个线程上的解决方案：Rails ExecJS::ProgramError in Pages#家？作品。我使用了第二个解决方案，它是最新的日期。

经过仔细研究，这是我偶然发现的解决方案。只需确保您安装了最新版本的NodeJs。安装 NodeJs 后，请确保您重新启动我们的系统。但是，更新 Windows 操作系统非常重要。你应该没事。如果您使用的是RubyMine，那么现在一切都应该正常了。无需为咖啡脚本问题烦恼。ExecJs 程序错误似乎与 NodeJs 及其相关模块更相关。

对我来说，解决方案是删除-

 <%= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track': 'reload'%>
 <%= javascript_include_tag 'application', 'data-turbolinks-track': 'reload' %>

从

app\views\layout\application.html.erb

The reason is because NodeJS is not installed. If you install it, the problem should go away.

However, this would work as well in application.js:

//= require jquery 
//= require jquery_ujs 
//= require turbolinks 
// require_tree .

But this is just not the prefered method because all this does is disable rails functionality. For example, ActionCable will not work with this change.

如果您不使用布局，请将“layout false”放在控制器文件中，就在类标题下方：

类 ABCController < ApplicationController "layout false" def index ... ..
