在Heroku上部署Hello World Sinatra应用程序问题。

Question

下面的代码：

# helloworld.rb 

require 'sinatra' 

get '/' do 
'Hello world! Welcome to the root!' 
end 

，当我部署到Heroku的我得到这个在我的日志：

我完全新的这一点，所以我认为我做错了什么或忘记包括一些东西。我刚刚得到H10应用程序崩溃错误和应用程序错误页面。

Answer 1

在你config.ru您需要更改

require 'helloworld' 

到

require './helloworld' 

这是在红宝石1.9.2，在当前目录中不再负载路径上进行了更改。如果这在你的本地机器上工作，那么你可以使用Ruby 1.8.7。如果是这种情况，那么值得升级到1.9.2。
