Question

我在我的application.js中有这个：

//= require jquery
//= require jquery_ujs
//= require prettyprint
//= require_tree .

这是我的生产配置：

  # Disable Rails's static asset server (Apache or nginx will already do this)
  config.serve_static_assets = false

  # Compress JavaScripts and CSS
  config.assets.compress = true

  # Don't fallback to assets pipeline if a precompiled asset is missed
  config.assets.compile = false

  # Generate digests for assets URLs
  config.assets.digest = true

当我推到Heroku时，我得到了：

-----> Writing config/database.yml to read from DATABASE_URL
-----> Preparing app for Rails asset pipeline
       Running: rake assets:precompile

但是当我在heroku中访问我的application.js时，文件是空白的。

更新

也许我没有说这是我的问题，但Heroku现在需要：

gem 'rails_12factor', group: :production

Gemfile中的

。我捆绑了。还没有工作。

我错过了什么？

Answer 1

您是否预先编译了您的资产： rake assets:precompile 在部署之前的cmd提示符中？

Answer 2

尝试替换以下内容：

Bundler.require(*Rails.groups(:assets => %w(development test)))

通过

Bundler.require(:default, :assets, Rails.env)

在application.rb文件中。

它应该是这样的：

if defined?(Bundler)
  # If you precompile assets before deploying to production, use this line
  # Bundler.require(*Rails.groups(:assets => %w(development test)))
  # If you want your assets lazily compiled in production, use this line
  Bundler.require(:default, :assets, Rails.env)
end

Answer 3

在生产中使用Ruby 1.9.3或将您的Rails版本升级到3.2.14或更高版本。

旧版本的Rails与Ruby 2.0不兼容。特别是链轮断裂：https://github.com/sstephenson/sprockets/issues/352

将来您应该考虑在Gemfile中锁定您的Ruby版本，以便在开发和生产中获得完全相同的体验。在您的Gemfile中添加：

ruby "2.0.0"

Rails资产管道不包括文件
