使用 Selenium 的 Chrome 驱动程序错误:无法发现打开的页面 [英] Chrome Driver Error using Selenium: Unable to Discover Open Pages

问题描述

我在运行 Selenium 测试时遇到与 Chrome 驱动程序相关的错误.错误消息是Unable to Discover Open Pages." Selenium 测试一直运行良好，直到昨晚.问题似乎是在前一天重新启动服务器后开始的.我无法在本地机器上重现此错误.从服务器上的命令行运行 Selenium 测试确实会打开 Chrome 浏览器，但会导致相同的错误.有什么想法吗?

I'm getting a Chrome Driver related error when running my Selenium tests. The error message is "Unable to Discover Open Pages." The Selenium tests were all running fine until last evening. The problem seemed to begin after a reboot of the server the day before. I cannot reproduce this error on my local box. Running the Selenium tests from the command line on the server does open the Chrome Browser but results in the same error. Any ideas?

失败的线路:

chromeDriver = new OpenQA.Selenium.Chrome.ChromeDriver(externalDriverPath);

错误消息和堆栈跟踪:

创建 ChromeDriver 实例时，会出现一个控制台窗口.出现错误的服务器似乎指的是未实现的东西.

When creating an instance of the ChromeDriver, a console window appears. The server with the error seems to refer to things NOT IMPLEMENTED.

来自服务器的 ChomeDriver 输出错误:

推荐答案

您正在使用 高度 过时的 ChromeDriver 版本.您的第一站应该是在这里更新它.

You are using a highly outdated version of the ChromeDriver. Your first port of call should be to update it here.

我高度怀疑问题在于您服务器上的 Chrome 已更新，而 ChromeDriver v2.1 没有 支持任何最新版本的 Chrome.

I would highly suspect the problem is your Chrome on your server has updated, and ChromeDriver v2.1 doesn't support any recent versions of Chrome.
