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
我也经历过这个问题,提出的解决方案似乎都不起作用。然后我发现问题是我在WSL版本1上运行,似乎chromedriver与windows浏览器一起工作,而不是与aptitude安装的浏览器。
为了使它与WSL版本1和版本2兼容,我发现(并在debian WSLv2和ubuntu WSLv1中进行了测试,它可以工作),该平台的版本显示的单词Microsoft的第一个大写字母。
所以解决方案是这样的:
import platform
from selenium.webdriver.chrome.service import Service as ChromeService
from seleniumwire import webdriver
chromedriver = 'chromedriver.exe'
# According to:
# https://stackoverflow.com/a/71879688/7019069
# When using WSL v1 the chromedriver.exe of local chrome of windows is used
# In WSL v2 (updated version) it does work using the installation shown in the README.md)
# And according to
# https://github.com/microsoft/WSL/issues/4555
# It is possible to differentiate the version of WSL by the first uppercase of the platform
# version of Microsoft. Therefore only the linux chromedriver is used if that word is matched
# in the platform of the driver.
if platform.system() == 'Linux' and not re.search(re.escape('Microsoft'), platform.platform()):
chromedriver = 'chromedriver'
driver_path = os.path.join(drivers_path, chromedriver)
service = ChromeService(driver_path)
driver = webdriver.Chrome(
service=service,
options=__get_chrome_options(headless)
)
我最近也面临着同样的问题,经过一些试验和错误,它也适用于我。
必须在最上面:
options.addArguments("--no-sandbox"); //has to be the very first option
BaseSeleniumTests.java
public abstract class BaseSeleniumTests {
private static final String CHROMEDRIVER_EXE = "chromedriver.exe";
private static final String IEDRIVER_EXE = "IEDriverServer.exe";
private static final String FFDRIVER_EXE = "geckodriver.exe";
protected WebDriver driver;
@Before
public void setUp() {
loadChromeDriver();
}
@After
public void tearDown() {
if (driver != null) {
driver.close();
driver.quit();
}
}
private void loadChromeDriver() {
ClassLoader classLoader = getClass().getClassLoader();
String filePath = classLoader.getResource(CHROMEDRIVER_EXE).getFile();
DesiredCapabilities capabilities = DesiredCapabilities.chrome();
ChromeDriverService service = new ChromeDriverService.Builder()
.usingDriverExecutable(new File(filePath))
.build();
ChromeOptions options = new ChromeOptions();
options.addArguments("--no-sandbox"); // Bypass OS security model, MUST BE THE VERY FIRST OPTION
options.addArguments("--headless");
options.setExperimentalOption("useAutomationExtension", false);
options.addArguments("start-maximized"); // open Browser in maximized mode
options.addArguments("disable-infobars"); // disabling infobars
options.addArguments("--disable-extensions"); // disabling extensions
options.addArguments("--disable-gpu"); // applicable to windows os only
options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
options.merge(capabilities);
this.driver = new ChromeDriver(service, options);
}
}
GoogleSearchPageTraditionalSeleniumTests.java
@RunWith(SpringRunner.class)
@SpringBootTest
public class GoogleSearchPageTraditionalSeleniumTests extends BaseSeleniumTests {
@Test
public void getSearchPage() {
this.driver.get("https://www.google.com");
WebElement element = this.driver.findElement(By.name("q"));
assertNotNull(element);
}
}

)
TL;DR:如果你使用VirtualBox共享文件夹,不要在那里创建Chrome配置文件!
我在Debian 10下遇到了这个错误,但在Ubuntu 18.04下没有发生。
在我的Selenium测试中,我想安装一个扩展,并使用以下Chrome选项:
chromeOptions.addArguments(
`load-extension=${this.extensionDir}`,
`user-data-dir=${this.profileDir}`,
`disable-gpu`,
`no-sandbox`,
`disable-setuid-sandbox`,
`disable-dev-shm-usage`,
);
问题是,我试图在一个非标准目录下创建一个Chrome配置文件,这是VirtualBox共享文件夹的一部分。尽管使用的是完全相同版本的Chrome和Chromedriver,但在Debian下却无法运行。
解决方案是在其他地方选择一个概要目录(例如~/chrome-profile)。
由于这是针对这类错误的最活跃的消息,所以我想提一下我的解决方案(在花了几个小时来修复这个问题之后)。
On Ubuntu 18.04, using Chrome 70 and Chromedriver 2.44, and Python3 I kept getting the same DevToolsActivePort error, even when I disabled all options listed above. The chromedriver log file as well as ps showed that the chromedriver I set in chrome_options.binary_location was running, but it always gave DevToolsActivePort error. When I removed chrome_options.binary_location='....' and add it to webdriver creation, I get it working fine.
webdriver.Chrome('/path to ... /chromedriver',chrome_options=chrome_options)
感谢大家的意见,让我理解并解决了这个问题。
我遇到了同样的问题,我使用UBUNTU, PYTHON和OPERA浏览器。在我的例子中,这个问题是因为我有一个过时的operadriver版本。
解决方案:
1. 确保您安装了最新的opera浏览器版本(不要使用opera beta或opera developer),为此请到opera官方网站并从那里下载最新的opera_stable版本。
安装最新的opera驱动程序(如果你已经安装了一个opera驱动程序,你必须先使用sudo rm删除它…)
wget https://github.com/operasoftware/operachromiumdriver/releases/download/v.80.0.3987.100/operadriver_linux64.zip
unzip operadriver_linux64.zip
sudo mv operadriver /usr/bin/operadriver
sudo chown root:root /usr/bin/operadriver
sudo chmod +x /usr/bin/operadriver
在我的情况下,最新的是80.0.3987,你可以看到
此外,我还安装了chromedriver(但因为我在测试之前做了,我不知道这是需要的),为了安装chromedriver,遵循上一步的步骤
好好享受吧,谢谢我!
