raise exception_class(value) selenium.common.exceptions.WebDriverException: Message: Parameters were incorrect. We wanted {"required":["desiredCapabilities"],"optional":["requiredCapabilities","sessionId","id","sessionId","id"]} and you sent ["capabilities","desiredCapabilities"]
如果出现上面错误 ，则可能是selenium版本太高，启用2.44版本即可，3.多的版本会出现上面这个错误
