org.openqa.selenium.WebDriverException：chrome无法访问 - 尝试启动新会话时 [英] org.openqa.selenium.WebDriverException: chrome not reachable - when attempting to start a new session

问题描述

当我在Chrome上运行测试时，我经常会遇到无法访问Chrome的WebdriverException。它不会每次都发生。也许每15次一次。我不得不在Windows机器上运行所有东西，我有最新的Chrome，Chromedriver，Selenium-Webdriver版本。

When I run my tests on Chrome I often get a WebdriverException that Chrome is not reachable. It doesn't happen every time. Maybe once every 15 times. I am having to run everything on Windows machines and I have the latest Chrome, Chromedriver, Selenium-Webdriver versions.

我尝试过设置环境变量DBUS_SESSION_BUS_ADDRESS = / dev / null。根本没有帮助。

I've tried setting the environmental variable "DBUS_SESSION_BUS_ADDRESS=/dev/null". Doesn't help at all.

有人遇到这个并找到了解决方案吗？

Anyone come across this and found a solution?

推荐答案

错误确实给了我们一些提示，如下所示：

The error does gives us some hint as follows :

org.openqa.selenium.WebDriverException: chrome not reachable

哪个ess实际意味着 chromedriver 二进制文件无法生成新的 Chrome浏览器进程。

Which essentially implies that chromedriver binary is unable to spawn a new Chrome Browser process.

您的主要问题是您使用的二进制文件中的版本兼容性，如下所示：

Your main issue is the version compatibility among the binaries you are using as follows :

• 您正在使用 chromedriver = 2.35.528161 （已发布 2018-01-10 ）


• <$ c的发行说明$ c> chromedriver = 2.35 明确提到以下内容：

• You are using chromedriver=2.35.528161 (released 2018-01-10)
• Release Notes of chromedriver=2.35 clearly mentions the following :

支持Chrome v62-64

Supports Chrome v62-64

• 您提到过使用最新的Chrome。我认为它是 chrome = 65.x


• 您正在使用 Selenium版本2.52.0 （已发布 2016-02-11 11:22:43 ）[根据错误堆栈在您的问题中跟踪]


• You mentioned of using latest Chrome. I suppose it is chrome=65.x
• You are using Selenium Version 2.52.0 (released 2016-02-11 11:22:43) [as per the error stack trace within your question]

因此 <$ c $发布之间的时间差距c> Selenium版本2.52.0 和 chromedriver = 2.35.528161 几乎 2年且不兼容。因此， ChromeDriver 有时无法生成新的 Chrome浏览器流程。

So the time gap between the release of Selenium Version 2.52.0 and chromedriver=2.35.528161 is almost 2 Years and are not compatible. Hence ChromeDriver is unable to spawn the new Chrome Browser process at times.



• 保持 ChromeDriver v2.35 级别。


• 降级 Chrome 稳定 Chrome v64.x 级别。 （根据ChromeDriver v2.35发行说明 ）


• 将 Selenium 升级到当前级别 版本3.8.1 。


• 执行测试。


• Keep the ChromeDriver at v2.35 level.
• Downgrade Chrome to stable Chrome v64.x levels. (as per ChromeDriver v2.35 release notes)
• Upgrade Selenium to current levels Version 3.8.1.
• Execute your Test.
