我试图用一个URL启动chrome浏览器，浏览器启动后，它什么也不做。
1分钟后我看到如下错误:
Unable to open browser with url: 'https://www.google.com' (Root cause: org.openqa.selenium.WebDriverException: unknown error: DevToolsActivePort file doesn't exist
(Driver info: chromedriver=2.39.562718 (9a2698cba08cf5a471a29d30c8b3e12becabb0e9),platform=Windows NT 10.0.15063 x86_64) (WARNING: The server did not provide any stacktrace information)
我的配置:
Chrome浏览器:66 ChromeBrowser: 2.39.56
又及，在Firefox中一切都很好
当前回答
更新conf.js中的功能
exports.config = {
seleniumAddress: 'http://localhost:4444/wd/hub',
specs: ['todo-spec.js'],
capabilities: {
browserName: 'chrome',
chromeOptions: {
args: ['--disable-gpu', '--no-sandbox', '--disable-extensions', '--disable-dev-shm-usage']
}
},
};
其他回答
我在Docker容器中通过Behat/Mink和Selenium运行Chrome时也遇到了同样的问题。经过一番折腾，我得出了如下结论。Yml提供上面提到的开关。请注意，要使它成功运行，所有这些都是必需的。
default:
extensions:
Behat\MinkExtension:
base_url: https://my.app/
default_session: selenium2
selenium2:
browser: chrome
capabilities:
extra_capabilities:
chromeOptions:
args:
- "headless"
- "no-sandbox"
- "disable-dev-shm-usage"
没有解决方法对我有效。但这里有一个变通办法:
maxcounter=5
for counter in range(maxcounter):
try:
driver = webdriver.Chrome(chrome_options=options,
service_log_path=logfile,
service_args=["--verbose", "--log-path=%s" % logfile])
break
except WebDriverException as e:
print("RETRYING INITIALIZATION OF WEBDRIVER! Error: %s" % str(e))
time.sleep(10)
if counter==maxcounter-1:
raise WebDriverException("Maximum number of selenium-firefox-webdriver-retries exceeded.")
更新:
我能够通过这个问题，现在我能够访问chrome所需的url。
对所提供解决方案的尝试结果:
我尝试了上面提供的所有设置，但我无法解决这个问题
关于问题的解释:
根据我的观察，DevToolsActivePort文件不存在的原因是chrome无法在scoped_dirXXXXX文件夹中找到它的引用。
为解决该问题所采取的步骤
我已经杀死了所有的chrome进程和chrome驱动程序进程。 添加下面的代码来调用chrome System.setProperty(“webdriver.chrome.driver”、“pathto \ \ chromedriver.exe”); ChromeOptions选项=新的ChromeOptions(); 选项。setExperimentalOption(“useAutomationExtension”,假); WebDriver驱动=新的ChromeDriver(选项); driver.get (url);
使用上述步骤，我能够解决这个问题。
谢谢你的回答。
I started seeing this problem on Monday 2018-06-04. Our tests run each weekday. It appears that the only thing that changed was the google-chrome version (which had been updated to current) JVM and Selenium were recent versions on Linux box ( Java 1.8.0_151, selenium 3.12.0, google-chrome 67.0.3396.62, and xvfb-run). Specifically adding the arguments "--no-sandbox" and "--disable-dev-shm-usage" stopped the error. I'll look into these issues to find more info about the effect, and other questions as in what triggered google-chrome to update.
ChromeOptions options = new ChromeOptions();
...
options.addArguments("--no-sandbox");
options.addArguments("--disable-dev-shm-usage");
我的端口号错了。检查启动Selenium服务器时的端口号是否与脚本中的端口号相同。
