我正在尝试将我们的 Rails3 应用程序从运行 Ruby 1.9.3 的旧 ElasticBeanstalk 环境迁移到运行 Ruby 2.0 的新环境。

一切似乎工作正常，除了资产预编译 javascript 文件上的“堆栈级别太深”错误（css 编译运行良好）。它在我安装了相同 Gems 的笔记本电脑上运行良好。下面是堆栈跟踪，任何建议都会有所帮助。提前致谢。

我终于找到了原因。那是因为这些代码行是为了支持 Emoji。

module ActiveSupport
  module JSON
    module Encoding
      class << self
        def escape_with_json_gem(string)
          ::JSON.generate([string])[1..-2]
        end
        alias_method_chain :escape, :json_gem
      end 
    end 
  end 
end
