require 'sinatra'
require 'rubygems'

class TestServer < Sinatra::Application
set :port,22340
    get '/' do
        "Hello World"
    end
    run! if app_file == $0
end

Ruby 2.0.0-p0和Sinatra 1.4.2的非常简单的应用程序

当我按ctrl-c时webrick服务器在默认端口上重新启动…请参阅下面的输出

任何人都可以帮我解决可能出现的问题吗？

解决方法

问题是你没有正确使用 Sinatra modular style.而不是要求sinatra和继承Sinatra :: Application你应该需要sinatra / base并继承Sinatra :: Base.

这是怎么回事.你需要简单的sinatra,而sinatra又需要sinatra / main.此文件为adds an at_exit handler that runs the built in server(除非您禁用它).但是你也明确地调用了run！在您自己的代码中,因此服务器因您的调用而启动,然后当您退出时,at_exit处理程序再次启动服务器.要求sinatra / base不会在退出时启动内置服务器,因此您只能拥有自己的显式调用来运行！

require 'sinatra/base' # change here
require 'rubygems'

class TestServer < Sinatra::Base # and here
  set :port,22340
  get '/' do
    "Hello World"
  end
  run! if app_file == $0
end
