selenium.common.exceptions.WebDriverException：消息：'chromedriver'可执...
当我运行我的脚本时，我收到了这个错误Traceback (most recent call last):

During handling of the above exception, another exception occurred:

selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home
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。
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")
