chromedriver azuredops 管道故障

Question

我正在尝试在 azure 管道中运行 selenium 测试，该测试在我的本地机器上运行良好：

options = webdriver.ChromeOptions()
options.add_argument('--no-sandbox')
options.add_argument('--disable-dev-shm-usage')
chrome_exe= ChromeDriverManager()
driver = webdriver.Chrome(executable_path=chrome_exe.install(), options=options)

但是当我在管道中运行相同时，它会失败并出现以下错误。

E       selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally.
E         (unknown error: DevToolsActivePort file doesn't exist)
E         (The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)

我手动转到它说的那条路径：没有这样的对象：chromedriver/84.0.4147.30 但如果我使用link 查询 它给出了相同的版本号

根据错误信息，Chrome 浏览器似乎没有安装在系统内的默认位置。

对于 Linux 系统，ChromeDriver 期望 /usr/bin/google-chrome 是实际 Chrome 二进制文件的符号链接。

如果您在非标准位置使用 Chrome 可执行文件，您可以尝试覆盖 Chrome 二进制位置，如下所示：

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()
options.binary_location = "C:\\path\\to\\chrome.exe"    #chrome binary location specified here
options.add_argument("--start-maximized") #open Browser in maximized mode
options.add_argument("--no-sandbox") #bypass OS security model
options.add_argument("--disable-dev-shm-usage") #overcome limited resource problems
options.add_experimental_option("excludeSwitches", ["enable-automation"])
options.add_experimental_option('useAutomationExtension', False)
driver = webdriver.Chrome(options=options, executable_path=r'C:\path\to\chromedriver.exe')
driver.get('http://google.com/')
