使用Watir时，“NameError：未初始化的常量UserAgent”

Question

我是ruby的新手，我似乎已经成功安装了watir-webdriver和webdriver-user-agent宝石，但当我试图按照说明here时，我偶然发现了。怎么办？

>> require 'watir-webdriver'
=> true
>> require 'webdriver-user-agent'
=> true
>> driver = UserAgent.driver(:browser => :chrome, :agent => :iphone, :orientation => :landscape)
NameError: uninitialized constant UserAgent
    from (irb):3
    from /usr/bin/irb:12:in `<main>'

Answer 1

尝试使用Webdriver::UserAgent
