机械化Sinatra冲突 [英] Mechanize & Sinatra conflict

问题描述

我使用 Mechanize 作为命令行实用程序编写了一个简单的Web搜寻器.然后，我决定使用 Sinatra 创建Web应用程序，但是在尝试运行本地Web服务器时陷入了该错误:

I've writter a simple web crawler using Mechanize as a command-line utility. Then I decided to create web app with Sinatra, but got stuck with this error when trying to run the local webserver:

/home/nazar/.rvm/gems/ruby-2.0.0-p195/gems/sinatra-1.4.2/lib/sinatra/base.rb:1569:in `run!': undefined method `run' for HTTP:Module (NoMethodError)
from /home/nazar/.rvm/gems/ruby-2.0.0-p195/gems/sinatra-1.4.2/lib/sinatra/main.rb:25:in `block in <module:Sinatra>'

源代码非常简单:

require 'sinatra'
require 'mechanize'

get '/' do
   # mechanize stuff
end

我已经进行了一些调查，并设法发现2颗宝石可以单独工作，但仅将它们结合使用会导致问题.谁能指出问题出在哪里?

I've gone through some investigation and managed to find out that 2 gems work fine separately, but only combining them causes the issue. Can anyone point out what the problem might be?

推荐答案

很可能您正在覆盖诸如get与mechanize之类的方法.尝试将您的Sinatra应用程序包装到应用程序类中.这样可以解决问题.

Most probably you are are overriding methods like get with mechanize. Try to wrap your Sinatra application into an application class. That may resolve the issue.

require 'sinatra/base'

class MyApp < Sinatra::Base
  get '/' do
    # mechanize stuff
  end
end
