rake资产:预编译不在heroku上工作

我的网站曾经在工作,Heroku预编译资产和一切。现在,似乎无处不在,我开始在部署时获得rake aborted! stack level too deep

从我的application.css文件中删除行*= require_tree .似乎修复了stack level too deep,但后来我明白了:

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)

我对图像的所有链接都被破坏了(我在我的css文件中使用了image-url())。可能是什么问题,我该如何解决?

我正在使用雪松堆栈,这是我的宝石文件:

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

以下是heroku使用的版本:

Using rake (0.8.7)
Using rails (3.1.0)
Using sass (3.1.15)
Using sass-rails (3.1.6)

这是我的application.rb文件

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

这是我的production.rb文件

# 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

我遇到了类似的问题,并在此处找到答案:https://github.com/rails/sass-rails/issues/78。基本上,降级到sass-rails v3.1.4。希望这有帮助

答案 1 :(得分:1)

您不应该从application.css中删除此*= require tree .,因为它会加载您的所有样式。只需添加它,并像这样配置config/production.rb文件:

config.assets.precompile = %w{application.js}

并运行RAILS_ENV =生产佣金资产:预编译

修改 尝试使用此配置:

config.assets.digest  = true

答案 2 :(得分:0)

显然sass停止了工作,我没有耐心,所以我决定不再使用它了。而不是这样做:

#theme.css.scss
background-image:image-url('image.png');

现在我只是使用erb文件:

#theme.css.erb
background-image:url(<%= asset_path 'image.png' %>);

因为这件事我只是失去了一整天,我不知道为什么因为它昨天工作正常。如果有人知道是什么导致了这个以及如何再次使用sass,请发表评论。
