我能够在本地运行rake asset：precompile，没有错误，但是输出表明资产已编译两次？

我注意到的几件事：

• 我没有咖啡脚本！ 为什么要搜索？
• 在任何情况下，咖啡轨宝石都与应用程序捆绑在一起
• 我似乎选择哪个配置设置来绑定application.rb中的资产组并不重要：

看到下面的代码：

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

有什么想法为什么不能在Heroku上对其进行预编译？

Answer 1

Heroku支持人员实际上无法确定失败的原因。 相反，他们问我

1. 将所有供应商/资产/ javascripts文件移至应用程序/资产/ javascripts
2. 将所有供应商/资产/样式表文件移动到应用程序/资产/样式表
3. 修改清单以将// = require_tree ../../../vendor替换为单个文件的require。

此外，不同的问题，但我不得不稍后修复此问题，也许现在修复它会有所帮助？？？ -

1. 将适当的文件添加到config / environments / production.rb中的config.assets.precompile中

他们说他们从未见过此问题，因此您可能希望与他们一起提出，以便引起适当的注意。

Answer 2

我不确定，但我认为问题出在rails_12factor gem。

我认为问题可能是因为coffee-rails宝石未正确加载。 由于这是Rails 3.2应用程序，因此您的Gemfile可能会在assets组中列出coffee-rails gem。 在Rails 4中，他们删除了assets组，因此，如果coffee-rails gem在assets组中，并且rails_12factor gem假定不是，则可能是问题所在。

另外，即使您尚未编写任何Coffeescript，但其中包含的某些宝石也可能需要Coffeescript。 实际上，他们对Coffeescript编译器的期望与对宝石的期望可能有所不同。
