rails 3.1在heroku .css上的部署不是预编译错误

更新

我收到此错误是因为我有一个public.css和public.js文件,该文件未使用其余的.css和.js文件进行编译.解决方案是将此行添加到production.rb文件中

# Precompile additional assets (application.js, application.css, and all non-JS/CSS are already added)
config.assets.precompile += %w( public.js public.css  )

从评论中可以看出,所有文件名应用程序都已添加.所以,我只需添加那些没有被称为应用程序的那些.

希望它可以帮到某人!

原始问题

我有这个宝石文件

gem 'rails', '3.1.0'

group :production do
  gem 'pg'
end
group :development, :test do
  gem 'sqlite3'
end

gem "heroku"
gem 'thin'
gem 'sass-rails', "  ~> 3.1.0"
gem 'coffee-rails', "~> 3.1.0"
gem 'tabulous'
gem 'json'
gem "paperclip", "~> 2.4"
gem "devise"
gem "redcarpet"

group :assets do

  gem 'uglifier'
end

gem 'jquery-rails'

gem "rspec-rails", :group => [:test, :development]
group :test do
end

当我使用"git push heroku master"进行部署时,我看到了这一点

但是在heroku日志中我得到了这个ActionView :: Template :: Error.css没有预编译奇怪..我认为它正在查看部署反馈

谁能看到我做错了什么？

运行bundle exec rake assets:precompile本地代码

提交更改并部署到heroku

如果这是您第一次将应用程序部署到heroku,则在解决此问题后可能会遇到更多错误.让我知道发生什么事.

实际上,您需要为生产环境运行预编译:

RAILS_ENV=production bundle exec rake assets:precompile在本地运行

提交并部署到Heroku

更广泛地说,Heroku文档描述了Cedar上Rails 3.1+资产编译的三个选项:

在本地编译(在此答案中介绍)

在slug编译期间编译

在运行时编译
