python – selenium.common.exceptions.WebDriverException：消息：’chromedriver’可执行文件需要在无头Chrome中出现PATH错误

[weixin_38073465]

当我运行我的脚本时,我收到了这个错误 Traceback (most recent call last): File "C:\Users\ishaq\AppData\Local\Programs\Python\Python36\lib\site-packages\selenium\webdriver\common\service.py", line 74, in start stdout=self.log_file, stderr=self.log_file) File "C:\Users\ishaq\AppData\Local\Programs\Python\Python36\lib\subprocess.py", line 707, in __init__ restore_signals, start_new_session) File "C:\Users\ishaq\AppData\Local\Programs\Python\Python36\lib\subprocess.py", line 992, in _execute_child startupinfo) FileNotFoundError: [WinError 2] The system cannot find the file specified During handling of the above exception, another exception occurred: Traceback (most recent call last): File "C:/Users/ishaq/AppData/Local/Programs/Python/Python36/headless.py", line 9, in <module> driver = webdriver.Chrome(executable_path=os.path.abspath("chromedriver"), chrome_options=chrome_options) File "C:\Users\ishaq\AppData\Local\Programs\Python\Python36\lib\site-packages\selenium\webdriver\chrome\webdriver.py", line 62, in __init__ self.service.start() File "C:\Users\ishaq\AppData\Local\Programs\Python\Python36\lib\site-packages\selenium\webdriver\common\service.py", line 81, in start os.path.basename(self.path), self.start_error_message) selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH.

如果我们分析日志似乎主要问题是在启动os.path.basename(self.path)和后续错误消息selenium.common.exceptions.WebDriverException：消息：’chromedriver’可执行文件需要在PATH中. 因此从错误中可以清楚地看出Python客户端无法找到chromedriver二进制文件. 你必须在这里处理几点： > chrome_options.binary_location：该参数配置chrome.exe而不是chromedriver.exe> os.path.abspath(“chromedriver”)将获取chromedriver的文件路径,但最后不会附加chromedriver.exe.>以下是我的Windows 8系统上以无头模式启动Chrome的示例代码： 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")
