Google chrome Watir webdriver和Chrome57；无法再使用'browser.window'`

我正在使用Watir webdriver、Chromedriver（v2.27）和Chrome（v57）实现自动化

我的spec_helper有一行代码，读作

@browser.window.maximize

自从更新到ChromeV57之后，当我返回以下错误时，它不再运行

Asset Section EULA and Intended Use The asset section behaves like eula and intended use EULA and Intended Use clicks Download and sees intended Use
 Failure/Error: @browser.window.maximize

我很有信心更新到v57会导致这种情况。它在我更新之前就已经工作了，而且——从现在开始——如果我在

@browser.window.maximize中注释，它会运行

有什么想法吗？
我也有同样的问题，最初通过删除browser.window.maximize并向开关添加以下内容来解决：

--start-maximized

该问题随后在ChromeDriver 2.28版（最新版本为2.29）中修复

ChromeDriver 2.28修复注释包括以下内容：

Fixes a bug which blocked ChromeDriver automation extension from loading and thereby causing window resizing/positioning & screenshot functionalities to break.

并且可以下载

同时检查测试输出以确保您实际使用的是下载的新驱动程序，您将看到类似“Starting ChromeDriver 2.xx.xxxxxx”的内容。您可能有一些配置指向ChromeDriver的旧版本。
Hmm。。。。我将chromedriver更新并重新启动到v2.29，并将我的开关改为现在的
开关：%w（--start maximized--ignore certificate errors--disable popup blocking--disable translate）
，我的测试不会在最大化的窗口中启动，开关不应该在数组中，因此方括号：开关：%w[--start maximized--ignore certificate errors--disable popup blocking--disable translate]做了一些额外的操作。我可以使用类似于
--start fullscreen
的东西，它占据整个屏幕。当我使用
--start maximized
时，它只有1011x1059的浏览器屏幕大小。有没有办法修改什么指的是“最大化”？有一个单独的开关可用于设置窗口大小：例如--ash host window bounds=“1024x768”。
