Question

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

当我按下ctrl-c时，webrick服务器会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？

问题是你没有正确使用Sinatra modular style。您需要sinatra并继承自Sinatra::Application，而非要求sinatra/base并继承Sinatra::Base。

这是怎么回事。您需要简单的sinatra，而sinatra/main则需要run!。此文件adds an at_exit handler that runs the built in server（除非您禁用它）。但是，您还在自己的代码中显式调用at_exit，因此服务器因您的调用而启动，然后当您退出时sinatra/base处理程序再次启动服务器。要求run!在退出时无法启动内置服务器，因此您只能自己显式调用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。
