Selenium WebDriverException

Question

我有一个使用硒中的webdriver的WebDriverException

[]# python3.4 file.py
Traceback (most recent call last):
  File "file.py", line 195, in <module>
    browser = webdriver.Firefox()
  File "/usr/lib/python3.4/site-packages/selenium/webdriver/firefox/webdriver.py", line 174, in __init__
    keep_alive=True)
  File "/usr/lib/python3.4/site-packages/selenium/webdriver/remote/webdriver.py", line 157, in __init__
    self.start_session(capabilities, browser_profile)
  File "/usr/lib/python3.4/site-packages/selenium/webdriver/remote/webdriver.py", line 252, in start_session
     response = self.execute(Command.NEW_SESSION, parameters)
  File "/usr/lib/python3.4/site-packages/selenium/webdriver/remote/webdriver.py", line 321, in execute
    self.error_handler.check_response(response)
  File "/usr/lib/python3.4/site-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

我读到此异常可能是由不同模块之间的版本问题引起的。但这里似乎不是问题。

Selnium版本：3.141

Geckodriver版本：0.26

Firfox版本：68.5.0esr

Python：3.4

你有什么想法吗？

src：

from selenium import webdriver
browser = webdriver.Firefox()
...

Answer 1

如果在没有显示的系统上运行Firefox，请确保使用无头模式。

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

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

此外，请确保您具有兼容的Firefox，Selenium和Geckodriver版本：https://firefox-source-docs.mozilla.org/testing/geckodriver/Support.html
