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

当我推送到 Heroku 时，我得到：

-----> 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

也许我没有提出这是我的问题，但 Heroku 现在需要：

gem 'rails_12factor', group: :production

在宝石文件中。我捆绑了。还没有工作。

我错过了什么？

要么在生产环境中使用 Ruby 1.9.3，要么将你的 Rails 版本升级到3.2.14或更高版本。

旧版本的 Rails 不能很好地与 Ruby 2.0 配合使用。特别是链轮断裂：https ://github.com/sstephenson/sprockets/issues/352

将来，您应该考虑锁定您的 Ruby 版本，Gemfile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"

rake assets:precompile 您是否在部署前在您的 cmd 提示符中预编译了您的资产 ？

尝试替换以下内容：

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

经过

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

在你的application.rb文件中。

它应该如下所示：

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
