无法在Selenium Grid中创建Chrome RemoteWebDriver

Question

我已经为这个问题苦苦挣扎了几天了。我无法在Selenium Grid中使用Chrome创建RemoteWebDriver。

集线器、节点和 Eclipse(触发测试(在一台机器上运行，但我也尝试了多台机器。

我在 Eclipse 中遇到异常：

Caused by: org.openqa.selenium.WebDriverException: unknown error: DevToolsActivePort file doesn't exist

以下是节点日志的内容：

11:57:26.208 INFO [ActiveSessionFactory.lambda$apply$11] - Matched factory

我想知道是什么原因导致两个 ChromeDriver 启动，第二个总是在端口 9515 上启动。我使用的是Chrome v67和Driver 2.40。

这是我的代码：

ChromeOptions options = new ChromeOptions();
options.addArguments("--no-sandbox");
options.addArguments("--disable-dev-shm-usage");
options.addArguments("--log-level=DEBUG");
options.addArguments("--dns-prefetch-disable");
options.setExperimentalOption("useAutomationExtension", false);
try {
WebDriver rwb = new RemoteWebDriver(new URL(hubAddress), options);
return rwb;
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

我已经尝试了你在谷歌或这里，在Stack上能找到的一切。无济于事。任何建议将不胜感激。提前谢谢。

此问题的解决方案是传递如下所示的 chromedriver 路径

java -jar-dwebdriver.chrome.driver=/users/username/Desktop/chromedriver24 Selenium-server-standalone-3.13.0.jar -role node -hub http://localhost:4444/grid/register -浏览器浏览器名称=chrome，max实例=3

而不是使用参数chrome_binary
