我需要从动态构建的页面获取数据，我找到的一个解决方案是 Watir。

irb 的下一个代码可以正常工作：

require 'rubygems'
require 'watir-webdriver'
require 'headless'

Headless.ly do
  browser = Watir::Browser.new :firefox
  browser.goto "google.com"
  browser.close
end

如果我尝试从 Rails 应用程序运行它有下一个问题：

宝石文件：

gem 'headless'
gem 'watir-webdriver'

行动：

def test_action
    Headless.ly do
          browser = Watir::Browser.new(:firefox)
          browser.goto "google.com"
          browser.close
     end
end

有下一个输出：

My project have the same errors with you

I found this question cauesed by the gem "selenium-webdriver"

and the verion should be '2.20.0'

If you gem's version is higher than this, this error would happen

just put this code in your initializers directory, works with 'watir-webdriver', '0.5.5'

require 'childprocess'
require 'tmpdir'
require 'fileutils'
require 'date'

require 'multi_json'
require 'selenium/webdriver/common'

module Selenium
  module WebDriver

    if MultiJson.respond_to?(:load)
      # @api private
      def self.json_load(obj)
        MultiJson.decode(obj)
        #MultiJson.load(obj) here was mistake
      end
    else
      # @api private
      def self.json_load(obj)
        MultiJson.decode(obj)
      end
    end

  end
end

这里讨论的问题

要解决它，您还可以尝试更新 multi_json gem，例如：

bundle update multi_json

对我来说，从版本 1.0.3 更新到 1.3.5 解决了这个问题。
