javascript - 如何解决 Python Selenium 错误 which

Question

我正在尝试使用 selenium 来处理一些使用 JavaScript 代码的网站。首先，我使用下面的简单示例

from selenium import webdriver

browser = webdriver.Firefox()

browser.get('http://www.yahoo.com')

browser.quit()

虽然这甚至不起作用。错误消息如下所示。我想我可能错过了 Selenium 或其他东西。你能给我一些启示吗？

Traceback (most recent call last):
  File "/home/rnie/webdriver-tutorial-1x.py", line 3, in <module>
    browser = webdriver.Firefox()
  File "/usr/lib/python3.5/site-packages/selenium/webdriver/firefox/webdriver.py", line 145, in __init__
    keep_alive=True)
  File "/usr/lib/python3.5/site-packages/selenium/webdriver/remote/webdriver.py", line 92, in __init__
    self.start_session(desired_capabilities, browser_profile)
  File "/usr/lib/python3.5/site-packages/selenium/webdriver/remote/webdriver.py", line 179, in start_session
    response = self.execute(Command.NEW_SESSION, capabilities)
  File "/usr/lib/python3.5/site-packages/selenium/webdriver/remote/webdriver.py", line 236, in execute
    self.error_handler.check_response(response)
  File "/usr/lib/python3.5/site-packages/selenium/webdriver/remote/errorhandler.py", line 192, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: connection refused

我检查了 “geckodriver.log”，它显示了以下错误消息:
