undetected-chromedriver版本不匹配：自动安装ChromeDriver无法适配需求

背景 #

在实例化新的undetected-chromedriver前，使用python-chromedriver-autoinstaller安装ChromeDriver：

import chromedriver_autoinstaller
chromedriver_autoinstaller.install()

# 输出显示安装了106版本的ChromeDriver
'C:\\Users\\username\\project_path\\lib\\site-packages\\chromedriver_autoinstaller\\106\\chromedriver.exe'

但执行UndetectedChromeDriver.Chrome(options=self._browser_options)时，抛出错误：

selenium.common.exceptions.WebDriverException: Message: unknown error: cannot connect to chrome at 127.0.0.1:... from session not created: This version of ChromeDriver only supports Chrome version 107 Current browser version is 106.0.5249.119

尝试使用webdriver-manager的常规方法同样无效：

from selenium.webdriver.chrome.service import Service as ChromeService
from webdriver_manager.chrome import ChromeDriverManager
import undetected_chromedriver as UndetectedChromeDriver

return UndetectedChromeDriver.Chrome(
    options=self._browser_options,
    service=ChromeService(ChromeDriverManager().install()))

需要一种支持远程部署、能自动获取并安装适配Chrome版本的ChromeDriver方案。

补充信息 #

通过注册表确认Chrome版本为106.0.5249.119：

C:\Users\username>REG QUERY HKEY_CURRENT_USER\Software\Google\Chrome\BLBeacon /v Version

HKEY_CURRENT_USER\Software\Google\Chrome\BLBeacon
    Version    REG_SZ    106.0.5249.119

解决方案 #

方法1：让undetected-chromedriver自动管理ChromeDriver #

undetected-chromedriver本身自带版本检测和安装功能，无需额外依赖第三方库：

import undetected_chromedriver as uc

# 自动匹配已安装的Chrome版本
driver = uc.Chrome(options=self._browser_options)

# 若自动匹配失效，强制指定Chrome主版本
driver = uc.Chrome(options=self._browser_options, version_main=106)

方法2：手动指定第三方库安装的ChromeDriver路径 #

如果坚持使用chromedriver-autoinstaller，需明确指定驱动路径：

import chromedriver_autoinstaller
import undetected_chromedriver as uc

# 安装并获取ChromeDriver路径
driver_path = chromedriver_autoinstaller.install()

# 实例化时指定路径
driver = uc.Chrome(options=self._browser_options, executable_path=driver_path)

方法3：锁定ChromeDriver版本（适用于webdriver-manager） #

使用webdriver-manager时，强制指定与Chrome匹配的驱动版本：

from selenium.webdriver.chrome.service import Service as ChromeService
from webdriver_manager.chrome import ChromeDriverManager
import undetected_chromedriver as uc

# 指定Chrome 106对应的ChromeDriver版本
driver = uc.Chrome(
    options=self._browser_options,
    service=ChromeService(ChromeDriverManager(version="106.0.5249.61").install())
)

注：ChromeDriver版本需与Chrome主版本一致，小版本可选择对应分支的最新版，比如Chrome 106对应ChromeDriver 106.0.5249.61
