org.openqa.selenium.WebDriverException: Timed out waiting for driver server to start using Selenium Chromedriver and Chrome on Linux Machine

Question

我正在尝试在 Linux 构建代理（在 Bamboo 中）中运行一些 Selenium 自动化测试，当我从 docker 运行它们时测试工作正常，但是当我直接在代理上安装 Chrome 和我需要的必要东西时运行它们，我收到以下错误。

Starting ChromeDriver 75.0.3770.140 (2d9f97485c7b07dc18a74666574f19176731995c-refs/branch-heads/3770@{#1155}) on port 9515
Only local connections are allowed.
Please protect ports used by ChromeDriver and related test frameworks to prevent access by malicious code.

我不知道这里出了什么问题，我的 docker 映像也具有与某些版本的 Chromedrivers 相同的操作系统。我哪里错了？

...暗示 ChromeDriver 无法启动/生成新的 WebBrowser 即 Chrome 浏览器 会话。

您的主要问题是您使用的二进制文件版本之间的不兼容性，如下所示：

• 您正在使用 chromedriver=75.0
• chromedriver=75.0 的发行说明明确提及以下内容：

支持Chrome 75版

• 大概您正在使用 chrome= 76.0
• ChromeDriver v76.0 的发行说明明确提及以下内容：

支持Chrome 76版

• 您的 Selenium Client 版本是 2017-08-29T12:42:44.417Z 的 3.5.3 版本，高于 2 岁以上。

因此 Selenium Client v3.5.1 、ChromeDriver v75.0 和 Chrome 浏览器 v76.0 之间存在明显的不匹配性 /p>

解决方案

确保：

• Selenium 升级到当前级别 Version 3.141.59。
• ChromeDriver 已更新到当前的ChromeDriver v76.0 级别。
• Chrome 已更新至当前 Chrome 版本 76.0 级别。 （根据ChromeDriver v76.0 release notes）
