selenium.common.exceptions.WebDriverException：消息：'chromedriver'可执...

马猴烧酒

当我运行我的脚本时，我收到了这个错误

During handling of the above exception, another exception occurred:

分析日志，主要问题是 start os.path.basename(self.path)和后续的错误消息selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH。
因此从上面消息中可以清楚地看出Python无法找到chromedriver二进制文件。
你必须在这里处理几点：
1.        chrome_options.binary_location：参数配置是chrome.exe而不chromedriver.exe
2.        os.path.abspath("chromedriver")将获取文件路径chromedriver但不会追加chromedriver.exe到最后。
3.        这里是Windows 8系统的示例代码，以Headless Mode运行chrome。

1. from selenium import webdriver  
   
2. from selenium.webdriver.chrome.options import Options
   
3. 
   
4. chrome_options = Options()  
   
5. chrome_options.add_argument("--headless")  
   
6. driver = webdriver.Chrome(chrome_options=chrome_options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')  
   
7. driver.get("http://www.duo.com")
   
8. print("Chrome Browser Initialized in Headless Mode")
   
9. driver.quit()
   
10. print("Driver Exited")
