Python Selenium启动浏览器报错[WinError193]：%1不是有效Win32应用

开发Python Selenium代码时，启动浏览器遭遇错误[WinError 193] %1 is not a valid Win32 application，经调试确认该问题与Selenium WebDriver相关。

报错堆栈信息如下：

Traceback (most recent call last):
  File "path/to/navegador.py", line 49, in iniciar_navegador
    navegador = webdriver.Chrome(service=servico, options=chrome_options)
                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "path/to/selenium/webdriver/chrome/webdriver.py", line 45, in __init__
    super().__init__(

    self.service.start()
  File "path/to/selenium/webdriver/common/service.py", line 98, in start
    self._start_process(self._path)
  File "path/to/selenium/webdriver/common/service.py", line 208, in _start_process
    self.process = subprocess.Popen(
                   ^^^^^^^^^^^^^^^^^

    hp, ht, pid, tid = _winapi.CreateProcess(executable, args,

解决该问题的关键是明确错误成因，首先通过以下代码检查ChromeDriver的安装路径：

driver_path = ChromeDriverManager().install()
print(f"ChromeDriver path: {driver_path}")

打印结果显示，程序获取的并非chromedriver.exe，而是其他类型文件：

ChromeDriver path: C:\Users\User\.wdm\drivers\chromedriver\win64\127.0.6533.72\chromedriver-win32/THIRD_PARTY_NOTICES.chromedriver

解决步骤：

• 打开文件资源管理器，进入上述打印的安装目录
• 删除目录中的LICENSE.chromedriver和THIRD_PARTY_NOTICES.chromedriver两个文件，仅保留chromedriver.exe
• 重新运行代码，浏览器即可正常启动，代码恢复正常运行
