我正在研究Rails 4(使用候选版本)项目,现在需要在Windows机器上与某人协作.我甚至无法得到一个基本的网页,但是:(即使使用Ruby 2.0安装sqlite3也是非常痛苦.现在,当我试图建立一个网页时(我刚刚创建了一个虚拟/家庭/索引控制器)和视图),我收到此错误:
Showing C:/Users/me/RubymineProjects/test_project/app/views/layouts/application.html.erb where line #6 raised:
(in C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/turbolinks-1.1.1/lib/assets/javascripts/turbolinks.js.coffee)
Extracted source (around line #6):
3 <head>
4 <title>TestProject</title>
5 <%= stylesheet_link_tag "application", media: "all", "data-turbolinks-track" => true %>
6 <%= javascript_include_tag "application", "data-turbolinks-track" => true %>
7 <%= csrf_meta_tags %>
8 </head>
9 <body>
Rails 4还没有为Windows做好准备吗？使用Ruby 2.0.0p195.
更新:根据@szines请求,这是网页输出

<%= stylesheet_link_tag "application", media: "all", "data-turbolinks-track" => true %>
将其更改为:
<%= stylesheet_link_tag "defaults", media: "all", "data-turbolinks-track" => true %>
它应该工作.
如果有人可以为此提供解释,那将是很棒的.
更多信息:
用户#index(RoR)中的ExecJS :: RuntimeError
只需安装node.js,问题就会消失.
说明:如果您尝试预编译资产,您将获得以下跟踪:
(in C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/turbolinks-1.3.0/lib/assets/javascripts/turbolinks.js.coffee)
C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/execjs-1.4.0/lib/execjs/external_runtime.rb:142:in `exec_runtime'
C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/execjs-1.4.0/lib/execjs/external_runtime.rb:28:in `block in exec'
C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/execjs-1.4.0/lib/execjs/external_runtime.rb:41:in `compile_to_tempfile'
...
如您所见,ExecJS存在问题.ExecJS允许您从Ruby运行JavaScript代码,它需要在您的系统上安装一个JS解释器.这是支持的口译员列表.通常,您可以使用仅仅是V8的therubyracer,但是在Windows下编译V8时会出现问题.所以你可以选择另一个选项 - NodeJS.当您安装NodeJS并将其添加到PATH时,ExecJS将自动使用它.
改变以下行
<%= javascript_include_tag "application", "data-turbolinks-track" => true %>
至
<%= javascript_include_tag "defaults", "data-turbolinks-track" => true %>
作品.
要么
你可以安装node.js.
