使用ChromeDriverManager指定win64下载ChromeDriver仍获取win32版本的问题

问题描述

尝试通过ChromeDriverManager强制下载win64版本的ChromeDriver，使用了以下代码：

if platform.system() == "Windows":
    driver_path = ChromeDriverManager(os_system_manager=OperationSystemManager(os_type="win64")).install()
    print(f"Driver path: {driver_path}")
else:
    driver_path = ChromeDriverManager().install()

但日志显示实际下载的是win32版本，且最终驱动路径指向win32目录下的文件：

解决方案

简化参数指定方式
新版本webdriver-manager已简化API，无需手动实例化OperationSystemManager，直接在ChromeDriverManager中传入os_type参数即可：

import platform
from webdriver_manager.chrome import ChromeDriverManager

if platform.system() == "Windows":
    driver_path = ChromeDriverManager(os_type="win64").install()
    print(f"Driver path: {driver_path}")
else:
    driver_path = ChromeDriverManager().install()

清理缓存目录
缓存中可能残留了win32版本的驱动文件，导致下载逻辑异常。手动删除日志中显示的缓存目录C:\Users\Administrator\.wdm\drivers\chromedriver\win64\143.0.7499.192，再重新运行代码。

修正驱动路径指向
日志中driver_path指向的是说明文件而非实际可执行文件，需手动指定chromedriver.exe路径：

import os
from selenium import webdriver

driver_exe_path = os.path.join(os.path.dirname(driver_path), "chromedriver.exe")
driver = webdriver.Chrome(executable_path=driver_exe_path)

升级webdriver-manager
旧版本库可能存在参数兼容问题，执行以下命令更新到最新版：
```
pip install --upgrade webdriver-manager
```
