耙资产：预编译不能在heroku上工作 [英] rake assets:precompile not working on heroku

问题描述

我的网站曾经工作过，Heroku预先编译了资产和一切。现在，看起来无处不在，我开始取消 rake！堆栈级别太深部署。

删除行 * = require_tree。 from我的application.css文件似乎修复了堆栈层太深，但是我得到这个：

 运行：rake资产：预编译
（in / tmp / build_b8o2t4k8frce）
 / usr / local / bin / ruby​​ /tmp/build_b8o2t4k8frce/vendor/bundle/ruby/1.9.1/ bin / rake资源：预编译：nondigest RAILS_ENV = production RAILS_GROUPS =资产
（in / tmp / build_b8o2t4k8frce）
  

我所有的图像链接都被打破了（我在我的css文件中使用了image-url（））。可能是这个问题，我该如何解决它？

我使用雪松堆栈，这是我的gemfile：

  gem'rails'，'3.1.0'
 gem'rake'，'0.8.7'
 gem'devise'
 
组：生产do 
 gem'pg'
 gem'瘦'
结束
 
组：资产do 
 gem'sass-rails' ，〜> 3.1.0
 gem'coffee-rails'，〜> 3.1.0
 gem'uglifier'
 end 
  
 使用rake（0.8.7）
使用rails（3.1.0）
使用sass（3.1.15）
使用sass-rails（3.1.6）
  
这是我的application.rb文件
  if defined？（Bundler）
＃如果您在部署到产品之前预编译资产，请使用以下命令：
 Bundler.require * Rails.groups（：assets =>％w（开发测试） ）
＃如果你希望你的资产在生产中被懒惰地编译，使用thi s行
＃Bundler.require（：default，：assets，Rails.env）
结尾
 
模块App 
 class Application< Rails :: Application 
 
＃启用资产管道
 config.assets.enabled = true 
 
＃您的资产版本，如果您想过期你的资产。 
 config.assets.version ='1.0'
 end 
 end 
  
这里是我的production.rb文件 
 
 
 ＃完全错误报告被禁用，缓存打开
 config。考虑_all_requests_local = false 
 config.action_controller.perform_caching = true 
 
＃启用Rails的静态资产服务器（Apache或nginx不需要这样）
 config.serve_static_assets = true 
 
＃为静态文件设置30天的过期标题
 config.static_cache_control =public，max-age = 2592000
 
＃允许JavaScript和CSS压缩
 config .assets.compress = true 
 
＃通过删除空格，缩短变量名称来压缩JavaScript 
 config.assets.js_compressor =：uglifier 
 
＃Don如果预编译的资产错过了，则回退到资产管道
 config.assets.compile = true 
 
＃为资产URL生成摘要
 config.assets.digest = true 
  
 
 
解决方案
我有类似的问题，并在这里找到答案： https://github.com/rails/sass-rails/issues/78 。基本上，降级到sass-rails v3.1.4。希望这有助于 
My website used to be working and Heroku precompiled the assets and everything. Now, seemingly out of nowhere, I started to get rake aborted! stack level too deep on deploy.

Deleting the line *= require_tree . from my application.css file seems to fix thestack level too deep but then I get this:
Running: rake assets:precompile
(in /tmp/build_b8o2t4k8frce)
/usr/local/bin/ruby /tmp/build_b8o2t4k8frce/vendor/bundle/ruby/1.9.1/bin/rake assets:precompile:nondigest RAILS_ENV=production RAILS_GROUPS=assets
(in /tmp/build_b8o2t4k8frce)
All my links to images are broken (I'm using image-url() in my css file). What could be the problem and how do I fix it?

I'm using cedar stack and this is my gemfile:
gem 'rails', '3.1.0'
gem 'rake', '0.8.7'
gem 'devise'

group :production do
  gem 'pg'
  gem 'thin'
end

group :assets do
  gem 'sass-rails', "  ~> 3.1.0"
  gem 'coffee-rails', "~> 3.1.0"
  gem 'uglifier'
end
And here are the versions used by heroku:
Using rake (0.8.7)
Using rails (3.1.0)
Using sass (3.1.15)
Using sass-rails (3.1.6)
Here's my application.rb file
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

module App
  class Application < Rails::Application

    # Enable the asset pipeline
    config.assets.enabled = true

    # Version of your assets, change this if you want to expire all your assets.
    config.assets.version = '1.0'
  end
end
And here's my production.rb file
# Full error reports are disabled and caching is turned on
config.consider_all_requests_local       = false
config.action_controller.perform_caching = true

# Enable Rails's static asset server (Apache or nginx will not need this)
config.serve_static_assets = true

# Set expire header of 30 days for static files
config.static_cache_control = "public, max-age=2592000"

# Allow JavaScript and CSS compression
config.assets.compress = true

# Compress JavaScript by removing whitespace, shortening variable names, ...
config.assets.js_compressor = :uglifier

# 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

I had a similar problem and found the answer here: https://github.com/rails/sass-rails/issues/78. Basically, downgrade to sass-rails v3.1.4. Hope this helps
