Chromedriver_autoinstaller 还在工作吗？

Question

我愿意运行chromedriver_autoinstaller。我在这里遵循示例：https://pypi.org/project/chromedriver-autoinstaller/

from selenium import webdriver
import chromedriver_autoinstaller


chromedriver_autoinstaller.install()  # Check if the current version of chromedriver exists
                                      # and if it doesn't exist, download it automatically,
                                      # then add chromedriver to path

driver = webdriver.Chrome()
driver.get("http://www.python.org")
assert "Python" in driver.title

但是我得到一个错误：

Traceback (most recent call last):

    exec(code, self.locals)
  File "<input>", line 9, in <module>

    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: unknown error: DevToolsActivePort file doesn't exist

这是什么意思？这个包还在用吗？

Answer 1

这个错误信息...

org.openqa.selenium.WebDriverException: unknown error: DevToolsActivePort file doesn't exist

...意味着 ChromeDriver 无法 initiate/spawn 一个新的 WebBrowser 即 Chrome 浏览器 会话。

A common cause for Chrome to crash during startup is running Chrome as root user (administrator) on Linux. While it is possible to work around this issue by passing --no-sandbox flag when creating your WebDriver session, such a configuration is unsupported and highly discouraged. You need to configure your environment to run Chrome as a regular user instead.

以普通用户身份执行测试。
