來自python selenium腳本的回溯錯誤（間歇性地工作）

Question

我用Python編寫了一個selenium腳本來自動發布到特定的網站。 我過去經營過它，它完美無缺。 但是，我去運行腳本，現在突然收到下面的內容。 我相信這是模塊加載的問題。 另外有時firefox會打開，有時則不會。 Linux上的Mac。

腳本：

from selenium import webdriver
browser = webdriver.Firefox()
browser.get('https://losangeles.craigslist.org/')

錯誤：

/usr/bin/python2.7 /home/max/Desktop/CraigsList.py
Traceback (most recent call last):
  File "/home/max/Desktop/CraigsList.py", line 4, in <module>
    browser = webdriver.Firefox()
  File "/home/max/.local/lib/python2.7/site-packages/selenium/webdriver/firefox/webdriver.py", line 81, in __init__
    self.binary, timeout)
  File "/home/max/.local/lib/python2.7/site-packages/selenium/webdriver/firefox/extension_connection.py", line 51, in __init__
    self.binary.launch_browser(self.profile, timeout=timeout)
  File "/home/max/.local/lib/python2.7/site-packages/selenium/webdriver/firefox/firefox_binary.py", line 68, in launch_browser
    self._wait_until_connectable(timeout=timeout)
  File "/home/max/.local/lib/python2.7/site-packages/selenium/webdriver/firefox/firefox_binary.py", line 98, in _wait_until_connectable
    raise WebDriverException("The browser appears to have exited "
selenium.common.exceptions.WebDriverException: Message: The browser appears to have exited before we could connect. If you specified a log_file in the FirefoxBinary constructor, check it for details.

Answer 1

1. 嘗試在控制台中運行FF，使用相同的用戶和路徑運行python腳本
2. 為webdriver設置log_file
3. 也許更好地使用PhantomJS驅動程序？
