    当我运行脚本时,出现了这个错误

    如果我们分析日志,主要问题似乎是 start os.path.basename(self.path) 和后续错误消息 selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH .

    chromedriver 二进制的

    你必须注意以下几点:

    1. chrome_options.binary_location :参数配置 chrome.exe 而不是 chromedriver.exe
    2. os.path.abspath("chromedriver") 镀铬驱动器 但不会追加 最后。
    3. Windows 8 要启动的系统 Chrome Headless Mode

      from selenium import webdriver  
      from selenium.webdriver.chrome.options import Options 
      
      chrome_options = Options()  
      chrome_options.add_argument("--headless")  
      driver = webdriver.Chrome(chrome_options=chrome_options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')  
      driver.get("http://www.duo.com") 
      print("Chrome Browser Initialized in Headless Mode")
      driver.quit()
      print("Driver Exited")
