#1 楼
如果我们分析日志，似乎主要问题出在start os.path.basename(self.path)和随后的错误消息selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH中。因此从错误中很明显，Python客户端无法找到
chromedriver二进制文件。这里您需要注意以下几点：
chrome_options.binary_location：该参数配置chrome.exe而不是chromedriver.exe os.path.abspath("chromedriver")将选择chromedriver的文件路径，但不会在末尾附加chromedriver.exe。这是我的
Windows 8系统上的示例代码，用于在Chrome中启动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")

另外，您也可以在无头模式下尝试Mozilla Firefox

我在Linux中有相同的错误。解决方法非常简单。只需运行此命令，错误就会消失。sudo apt install chromium-chromedriver

错误消息的可能重复：“'chromedriver'可执行文件必须在路径中可用”在发布问题之前，您应该花一些时间阅读错误消息并尝试了解错误是什么。然后，您应该花一些时间搜索错误，以便更好地了解错误的含义以及人们如何解决这些错误。这是一个常见错误，如果您花时间寻找它，那么已经有了解决方案。
@JeffC实际上我对os.path和binary.location感到困惑。我对此进行了大量搜索，但没有找到解决方案，这就是为什么我发布了这个问题。
