Ruby Sinatra在ctrl-c之后重新启动Webrick服务器

有人能帮我解决这里可能出现的问题吗

问题是您没有正确使用。与其要求

sinatra

并从

sinatra:：Application

继承，不如要求

sinatra/base

并从

sinatra:：base

继承

发生的事情就是这样。您需要普通的

sinatra

，这反过来又需要

sinatra/main

。此文件（除非禁用）。但是，您也可以显式地调用

run

在您自己的代码中，因此服务器会因为您的调用而启动，然后当您退出时，

at_exit

处理程序会再次启动服务器。需要

sinatra/base

不会在退出时启动内置服务器，因此您只需要自己显式调用

run

require'sinatra/base'#此处更改
需要“rubygems”
