ruby-on-rails - Javascript manifest file "application.js" is not processed

Question

I am on a Macbook Pro and I created a new Rails 3.2 app, but the assets pipeline does not work. Here is what I did:

$ rails version
  Rails 3.2.5
$ rails new test_assets
$ cd test_assets
$ rails server

The server is started OK, but if I visit http://0.0.0.0:3000/assets/application.js, it turns out the manifest file is not processed at all, it shows:

//... some comments ...
//= require jquery
//= require jquery_ujs
//= require_tree .
;

I tried to do the exactly the same steps on my other Macbook Pro. It works well. Visiting http://0.0.0.0:3000/assets/application.js on that machine shows a compiled javascript file with all the contents.

I have read http://railscasts.com/episodes/279-understanding-the-asset-pipeline and http://guides.rubyonrails.org/asset_pipeline.html, and I searched for hours on the web but with no clue.

Your help is really appreciated!

建议：安装 node.js 或gem 'therubyracer', :platforms => :ruby在 Gemfile 中取消注释

我遵循相同的步骤，我的日志文件看起来像这样......如果你启动服务器并请求 /assets/application.js，你的会是什么样子？如您所见，我使用的是 3.2.6，它编译了我的 application.js

我遇到过同样的问题！

将 Ruby 从 2.0.0 降级到 1.9.3 解决了这个问题

面临完全相同的情况。

我发现我使用像 v2.0.0rc 之类的 ruby 或类似的东西，如果我将它降级到 1.9.3p194（两者都在 Rbenv 下），一切都会完美。

尽管您可以在视图中使用 helper，例如<%= javascript_include_tag "jquery", "jquery_ujs" %>，但即使使用 ruby2.0.0，它也对我有所帮助。

我今天遇到了同样的问题，我准备将 Ruby 从 2.0 降级到 1.9.3 以解决 application.js 无法编译的问题。该问题发生在安装了 Ruby 2.0（和 Rails 3.2.8）的生产服务器上。在开发机器上（Ruby 1.9.3 和 Rails 3.2.8）application.js 编译得很好。

最后，我将生产服务器从 Rails 3.2.8 升级到 3.2.14；删除 Gemfile.lock，然后运行 bundle install。然后我重新编译了资产，瞧，application.js 编译了资产。

我想与 Stackoverflow 的观众分享这个，也许这会解决别人的问题。

使用 ruby 2.0 的第一个官方支持的 rails 3.2 版本是 3.2.13。因此将您的 rails 版本升级到 rails 3.2.13 将解决问题。

升级步骤：

1) 将 Gemfile 中的 rails 版本更改为 gem 'rails', '3.2.22'。

2）捆绑更新轨道

在开发时，资产没有预编译。如果你想看到它们，你应该运行bundle exec rake assets:precompile.

打开 enviornment/development.rb 并设置 config.assets.debug = false 。而已
