以下是我用来从选择标签中选择一个特定选项的代码：

       select = driver.find_element(:id, "lang")
       wait = Selenium::WebDriver::Wait.new(:timeout => 20)
       begin
         all_options = wait.until { driver.find_elements(:tag_name => "option") }
       end
       all_options.each do |option|
             if (option.attribute("value")=="11")
                 option.click
             end
       end

我正在使用 jruby。当我在 IRB 中逐行执行命令时，没有问题。但是，当我一起运行整个代码时，它给了我一个意外的文件结束错误。为什么我会收到此错误？为什么它在逐个命令执行时起作用，而不是在整体执行时起作用？我该如何克服呢？

错误如下 -

你有太多的目的：

 begin <--- remove this
     all_options = wait.until { driver.find_elements(:tag_name => "option") }
   end <--- remove this
   all_options.each do |option|
         if (option.attribute("value")=="11")
             option.click
         end
   end

或者，如果您需要救援：

 begin
     all_options = wait.until { driver.find_elements(:tag_name => "option") }
  rescue
     do someting
  end 
   all_options.each do |option|
         if (option.attribute("value")=="11")
             option.click
         end
   end
