Question

我使用selenium-webdriver自动化基于CefSharp（CEF3）的应用程序，但不断出现错误。

我使用以下Ruby脚本启动CEF应用程序：

require "selenium-webdriver"
cefpath = 'C:\mypathto\cefapp.exe'
Selenium::WebDriver::Chrome.path = cefpath
browser = Selenium::WebDriver.for :chrome
......

运行时，它会打开CEF应用程序（Chrome的容器），但随后出现以下错误：

知道为什么吗？

非常感谢。

确保使用最新的ChromiumDriver / Selenium版本。根据这个：

CEF适用于ChromeDriver版本2.14和Selenium 2.44.0。
