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

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。

其他回答

在尝试在Linux服务器上运行selenium时遇到了同样的问题,尝试降级你的chrome版本,它对我有用吗

从这里选择版本

http://170.210.201.179/linux/chrome/deb/pool/main/g/google-chrome-stable/

对我来说,问题在于systemD服务文件。我将shell环境传递为venv

Environment="proejct/venv/bin"

当我添加/bin:/usr/bin到Environment:

Environment="proejct/venv/bin:/usr/bin:/bin"

最后,它成功了。

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!

示例硒代码

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
driver = webdriver.Opera()
driver.get("http://www.python.org")
assert "Python" in driver.title
elem = driver.find_element_by_name("q")
elem.clear()
elem.send_keys("pycon")
elem.send_keys(Keys.RETURN)
assert "No results found." not in driver.page_source
driver.quit()

正如在另一个答案中所述:

此错误消息…这意味着ChromeDriver无法启动/生成一个新的WebBrowser,即Chrome浏览器会话。

Among the possible causes, I would like to mention the fact that, in case you are running an headless Chromium via Xvfb, you might need to export the DISPLAY variable: in my case, I had in place (as recommended) the --disable-dev-shm-usage and --no-sandbox options, everything was running fine, but in a new installation running the latest (at the time of writing) Ubuntu 18.04 this error started to occurr, and the only possible fix was to execute an export DISPLAY=":20" (having previously started Xvfb with Xvfb :20&).

如果添加参数/选项不能解决问题,那么可能是/tmp目录的权限问题。

确保执行Chrome的用户有权限在/tmp文件夹下创建文件夹/files。这就是我案例中的解
