Selenium WebDriver 错误：ChromeDriver 版本不匹配和元素未找到

在使用 Selenium WebDriver 自动化测试时，可能会遇到各种错误。以下是两个常见的错误示例，并提供相应的解决方案：

1. ChromeDriver 版本不匹配

DevTools listening on ws://127.0.0.1:2265/devtools/browser/3e079511-213b-4203-8699-0faa658c1519
Traceback (most recent call last):

    driver = webdriver.Chrome(options=options)

    RemoteWebDriver.__init__(

    response = self.execute(Command.NEW_SESSION, parameters)
  File "C:\Python3\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 321, in execute
    self.error_handler.check_response(response)
  File "C:\Python3\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 100
Current browser version is 96.0.4664.93 with binary path C:\Users\Administrator\AppData\Local\Google\Chrome\Application\chrome.exe

**错误原因：**ChromeDriver 版本与 Chrome 浏览器版本不匹配。

解决方案：

  • 确保 ChromeDriver 的版本与 Chrome 浏览器的版本相匹配。您可以从 ChromeDriver 下载页面 下载与您的 Chrome 版本对应的 ChromeDriver。
  • 将 ChromeDriver 文件放置在系统 PATH 环境变量中，以便 Selenium 能够找到它。

2. 找不到元素

什么问题

错误原因：

  • 页面加载不完全：元素可能尚未加载完成，导致 Selenium 无法找到它。
  • 元素不存在：网页代码中可能根本不存在该元素。

解决方案：

  • 使用显式等待：使用 WebDriverWait 和 expected_conditions 来等待元素出现，例如：
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

wait = WebDriverWait(driver, 10)  # 设置等待时间为 10 秒
button = wait.until(EC.presence_of_element_located((By.CLASS_NAME, 'more-btn')))
  • 检查网页代码：确认页面代码中是否确实存在 class 为 'more-btn' 的元素。
  • 使用其他定位器：尝试使用其他定位器，例如 ID 或 Xpath，来定位元素。

总结：

  • ChromeDriver 版本不匹配是一个常见的错误，确保 ChromeDriver 的版本与 Chrome 浏览器的版本相匹配。
  • 元素未找到可能是页面加载不完全或元素不存在导致的，可以使用显式等待或其他定位器来解决问题。
