Heroku Sinatra应用程序 - 未初始化的恒定Jido

时间：2011-02-17 03:43:49

标签： ruby heroku sinatra require

我有一个小的Sinatra应用程序正在调用我开发的名为Jido的库。这个库由RubyGem提供，我在Sinatra应用程序的Gemfile中列为依赖项。我可以在运行Ruby 1.9.2的本地计算机上运行此应用程序而不会遇到任何错误。但是，当我推送到Heroku并访问使用此“Jido”库的页面时，服务器返回错误。从日志中我看到Heroku服务器正在运行Ruby 1.8.7。这是Heroku错误日志中的堆栈跟踪：

在我的主要Sinatra脚本中与此错误相关的行：

require 'rubygems'
require 'sinatra'

require 'json'
require 'jido'

conjugators = {}
get '/conjugate/:lang/:verb' do
    content_type :json

    conjugator = nil
    if conjugators[params[:lang]].nil?
    conjugator = Jido.load params[:lang] # exception "Uninitialized constant Jido" is thrown here
    conjugators[params[:lang]] = conjugator
    else conjugator = conjugators[params[:lang]] end

    conjugator.conjugate(params[:verb]).to_json
end

正如我所说，这个代码在我的机器上使用Ruby 1.9.2运行良好。我已经测试过从Sinatra应用程序和IRB调用这个Jido模块 - 两者都运行没有问题。我看到当我按照我的Gemfile要求安装jido gem时，我会看到，但由于某些原因我无法在我的Sinatra脚本中引用它...任何想法？

Sinatra应用程序的完整源代码（包括Gemfile和Gemfile.lock）可在https://github.com/hans/jido-site获得。

我切换到bamboo-mri-1.9.2堆栈（我之前在bamboo-mri-1.8.7堆栈上）并修复了它。非常感谢TK-421的帮助！
