问题
I'm working on a Rails 4 (using the release candidate) project and now need to collaborate with someone on a Windows machine. I can't even get a basic webpage to come up, however :(. It was quite a pain even installing sqlite3 using Ruby 2.0. Now, when I try to get a webpage up (I just created a dummy /home/index controller and view), I get this error:
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>
Is Rails 4 just not ready for Windows yet? Using Ruby 2.0.0p195.

<%= stylesheet_link_tag "application", media: "all", "data-turbolinks-track" => true %>
Change this to :
<%= stylesheet_link_tag "defaults", media: "all", "data-turbolinks-track" => true %>
It should work.
It will be great if someone can provide explanation for this.

ExecJS and could not find a JavaScript runtime

Just install node.js and the problem will gone.
Explanation: If you'll try to precompile assets, you'll get the following trace:
(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'
...
As you can see, there is a problem with ExecJS. ExecJS lets you run JavaScript code from Ruby and it requires one of the JS interpreters to be installed on your system. Here's a list of supported interpreters. Usually, you can use therubyracer which is just V8 but there are problems with compiling V8 under the windows. So you can choose another option - NodeJS. ExecJS will use it automatically when you'll install NodeJS and add it to your PATH.

changing following line
<%= javascript_include_tag "application", "data-turbolinks-track" => true %>
to
<%= javascript_include_tag "defaults", "data-turbolinks-track" => true %>
works.
OR
you can install node.js

The actual solution for getting Turbolinks to work on Windows 8 x64 is posted at ExecJS::RuntimeError on Windows trying to follow rubytutorial, option 3.

I have been facing this problem for a while and it's that on windows jquery and coffee script are not functional in their latest update and finally i found this wonderful method that worked perfectly without the need to download node or escape //require tree. So all you need is configure the settings in your runtimes.rb which lives in execjs to be like this- you will find this part with few differences fix them and you'll be good to go.
JScript = ExternalRuntime.new(
:name => "JScript",
:command => "cscript //E:jscript //Nologo",
:runner_path => ExecJS.root + "/support/jscript_runner.js",
:encoding => 'UTF-8' # CScript with //U returns UTF-16LE
