Question

我有rails应用程序，它们在本地计算机上运行良好。但是当我在Heroku上部署它时，我在浏览器中出现了下一个错误：

Failed to load resource: the server responded with a status of 404 (Not Found) http://hollow-cloud-nnn.herokuapp.com/stylesheets/application.css
Failed to load resource: the server responded with a status of 404 (Not Found) http://hollow-cloud-nnn.herokuapp.com/javascripts/application.js

我在app \ assets \ javascript和\ app \ assets \ stylesheets文件夹中有这些文件。

这是我的config \ production.rb：

# 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 = true

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

以下是部署的控制台输出：

       Using mongoid (2.4.7)
       Using rails (3.2.1)
       Using sass (3.1.15)
       Using sass-rails (3.2.5)

我该如何解决？

Answer 1

您应该在生产环境中precompile assets或设置config.assets.compile = true。

有关heroku开发中心的更多信息，请阅读how to use rails 3.1+ asset pipeline on heroku。

Answer 2

好像你是一个运行rails 3.1+的mongoid用户。对于Mongoid用户来说，这是一个非常常见的问题，因为文档指示您在config/application.rb中删除此行

require 'rails/all'

要解决此问题，请将以下行添加到config/application.rb

require 'sprocket/railtie'
