python - WebDriverException : Message: invalid argument: can't kill an exited process with GeckoDriver, RaspberryPi3 上的 Selenium 和 Python

Question

服务器:Raspberry Pi 3
操作系统:Dietpi - 版本 159
Geckodriver 版本:arm 0.22
火狐版本:52.9.0
Python版本:3.5
Selenium 版本:3.14.1

Gecko 是可执行的，位于/usr/local/bin/

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.firefox.options import Options
import time



options = Options()
options.set_headless(headless=True)
driver = webdriver.Firefox(firefox_options=options)

print('Need your login credential')
username = input('What is your username?:\n')
password = input('What is your password?:\n')
...
...

输出:

root@RPi3:~# python3.5 ITE-bot.py 
Traceback (most recent call last):
  File "ITE-bot.py", line 12, in <module>
    driver = webdriver.Firefox(firefox_options=options)

    self.start_session(capabilities, browser_profile)

    response = self.execute(Command.NEW_SESSION, parameters)
  File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/remote/webdriver.py", line 321, in execute
    self.error_handler.check_response(response)
  File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/remote/errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: invalid argument: can't kill an exited process

知道出了什么问题吗？我尝试过谷歌但没有成功。

如果您在没有显示屏的系统上运行 Firefox，请确保使用 headless 模式。

from selenium import webdriver
from selenium.webdriver.firefox.options import Options

options = Options()
options.headless = True
driver = webdriver.Firefox(options=options)

此外，请确保您拥有 Firefox、Selenium 和 Geckodriver 的兼容版本: https://firefox-source-docs.mozilla.org/testing/geckodriver/Support.html
