当使用selenium-webdriver的警报方法时,我遇到了JavaScript错误:"e is null"

码:

browser = Watir::Browser.new :firefox
browser.alert.ok; sleep 5

错误:

Selenium::WebDriver::Error::UnknownError: [JavaScript Error: "e is null" {file: "file:///var/folders/f4/rz3xgqkj22zdyldyzrnyx4v40000gn/T/webdriver-profile20140731-47367-tyngix/extensions/fxdriver@googlecode.com/components/command_processor.js" line: 7716}]'
[JavaScript Error: "e is null" {file: "file:///var/folders/f4/rz3xgqkj22zdyldyzrnyx4v40000gn/T/webdriver-profile20140731-47367-tyngix/extensions/fxdriver@googlecode.com/components/command_processor.js"
line: 7716}]' when calling method: [nsICommandProcessor::execute]

环境:

• 'selenium-webdriver','2.42.0'
• Firefox 31.0
• MAC 10.9
• Ruby 2.0

任何建议将非常感谢.谢谢!
