您正在使用chromediver 2.32并在release notes中写道支持适用于 Chrome v59-61

作为浏览器:

Chrome Version 62.0.3202.62 (Official Build) (64-bit) 

因此,从ChromeDriver开始,你应该使用2.33

答案 1 :(得分:21)

我有类似的错误。但版本匹配:我使用的是Chrome 65,驱动程序版本为2.38。

我花了很长时间,试图理解这个问题。 最后,发现它是由空/etc/hosts文件引起的。显然,Chrome通过localhost进行通信,如果/etc/hosts中缺少此类条目,则会崩溃。

所以,请确保它有这样的条目:

127.0.0.1 localhost

这是@ davide-patti解决方案的brew附录。 :)

当我收到错误unable to connect to renderer时,我从中学习 @ davide-patti我使用的是较旧版本的chromedriver,v2.32。但我无法将chromedriver升级为主brew,因为我不断收到:No available formula with the name "chromedriver"

本文帮助我升级到v2.33 +。

关于:错误:没有名为“chromedriver”的可用公式 https://github.com/Homebrew/brew/issues/4089

这是因为页面加载时间较长,您需要在脚本中添加其他行

System.setProperty("webdriver.chrome.driver","E:\\selenium\\chromedriver_2.41\\chromedriver.exe");
//mention the below chrome option to solve timeout exception issue
ChromeOptions options = new ChromeOptions();
options.setPageLoadStrategy(PageLoadStrategy.NONE);
// Instantiate the chrome driver
driver = new ChromeDriver(options);
