Python、eclipse、mac都在努力让selenium正常工作

我安装了selenium包，现在尝试在eclipse中运行它。它似乎导入良好，但它不会加载任何浏览器的webdriver。这就是它给出的错误

driver = webdriver.Firefox()
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/selenium-2.45.0-py2.7.egg/selenium/webdriver/firefox/webdriver.py", line 59, in __init__
    self.binary, timeout),

  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/selenium-2.45.0-py2.7.egg/selenium/webdriver/firefox/extension_connection.py", line 47, in __init__
    self.binary.launch_browser(self.profile)

  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/selenium-2.45.0-py2.7.egg/selenium/webdriver/firefox/firefox_binary.py", line 65, in launch_browser
    self._start_from_profile_path(self.profile.path)

    env=self._firefox_env).communicate()

我检查过了，文件夹和文件都在那里，所以我不知道发生了什么。任何帮助都将不胜感激。

您是否安装了firefox？@alecxe-oops！！！我觉得自己太笨了，我没有安装它。我没有意识到我需要这样做，因为我认为驱动程序将从selenium捆绑包中使用。谢谢你指出我的愚蠢！现在效果很好。
