设置方法watir无效参数错误

Question

我正在使用watir和ruby编写页面对象模式UI框架。这是工作的罚款，直到我做了捆绑更新

我表示这种

username: 
field: text_field 
attribute: name 
value: username 
default: 
operations: 
    - exists? 
    - set 

，以及页对象方法生成此送入

def generate(elements) 
    elements.each do |element| 
     element[1]['operations'].each do |operation| 
      if operation.eql? 'set' 
       default = element[1]['default'] 
       self.class.send(:define_method, "#{element[0]}_#{operation}") do |default=''| 
        @b.send(element[1]['field'], element[1]['attribute'].to_sym, element[1]['value']).send(operation, default) 
       end 
      else 
       self.class.send(:define_method, "#{element[0]}_#{operation}") do 
        @b.send(element[1]['field'], element[1]['attribute'].to_sym, element[1]['value']).send(operation) 
       end 
      end 
     end 
    end 
end 

当我页面的YML文件对铬进行watir测试，这似乎工作正常。然而，当我的浏览器是火狐，我得到一个错误Expected [object Undefined] undefined to be a string (Selenium::WebDriver::Error::InvalidArgumentError)

6号线的产生方法是抛出的错误

这是我如何通过阳明的生成方法

def initialize(browser) 
    file_path = File.expand_path("../config/signin.yml", __FILE__) 
    elements = YAML.load(File.read(file_path)); 
    super(browser, elements) 
end 

的Watir版本6.8.0 硒的webdriver版本3.5.1 geckodriver辅助0.0.3

UPDATE

我看着我自己的问题，我张贴，并在我的代码。意识到我提到了bundle update搞砸了可执行代码，我看了一下我的Gemfile。我能够发现罪魁祸首是geckodriver-helper这是打破geckodriver，我通过homebrew安装。

教训：无论是通过自制软件或者Gemfile文件但不能同时
