尝试动态创建对象和调用方法

Object.const_get(class_name).new.send(method_name,parameters_array)

这工作正常

Object.const_get(RandomClass).new.send(i_take_arguments,[10.0])

但为2输入错误数量的参数1

Object.const_get(RandomClass).new.send(i_take_multiple_arguments,[25.0,26.0])

定义的随机类是

class RandomClass
def i_am_method_one
    puts "I am method 1"
end
def i_take_arguments(a)
    puts "the argument passed is #{a}"
end
def i_take_multiple_arguments(b,c)
    puts "the arguments passed are #{b} and #{c}"
end
    end

有人可以帮助我如何动态地发送多个参数到ruby方法

在 watir 文档（http://watir.com/guides/chrome/）中，已经提到做

Watir::Browser.new :chrome, headless: true

将使我们能够使用无头 chrome

这似乎不起作用。

我收到如下错误
