硒（用python/django）无法启动firefox浏览器实例

我刚刚使用pip安装了硒。当我启动一个django shell时，我可以从selenium导入模块。而下面的语句将失败：硒（用python/django）无法启动firefox浏览器实例

self.browser = webdriver.Firefox()

，出现以下错误：

Traceback (most recent call last): 
    File "/opt/my_apps/cpns/core/tests.py", line 771, in setUp 
    self.browser = webdriver.Firefox() 
    File "/opt/my_apps/cpns/build/lib/python2.7/site-packages/selenium/webdriver/firefox/webdriver.py", line 59, in __init__ 
    self.binary, timeout), 
    File "/opt/my_apps/cpns/build/lib/python2.7/site-packages/selenium/webdriver/firefox/extension_connection.py", line 47, in __init__ 
    self.binary.launch_browser(self.profile) 
    File "/opt/my_apps/cpns/build/lib/python2.7/site-packages/selenium/webdriver/firefox/firefox_binary.py", line 61, in launch_browser 
    self._wait_until_connectable() 
    File "/opt/my_apps/cpns/build/lib/python2.7/site-packages/selenium/webdriver/firefox/firefox_binary.py", line 100, in _wait_until_connectable 
    self._get_firefox_output()) 
WebDriverException: Message: "The browser appears to have exited before we could connect. The output was: XPCOMGlueLoad error for file /usr/bin/libxpcom.so:\n/usr/bin/libxpcom.so: cannot open shared object file: No such file or directory\nCouldn't load XPCOM.\n"

我想执行的代码是非常基本的。我在网上抄了一遍：

class GoogleTestCase(TestCase): 

    def setUp(self): 
     self.browser = webdriver.Firefox() 
     self.addCleanup(self.browser.quit) 

    def testPageTitle(self): 
     self.browser.get('http://www.google.com') 
     self.assertIn('Google', self.browser.title)

我相信它有更多的是与Firefox安装本身，而不是硒，但在任何情况下，任何帮助将不胜感激。

http://stackoverflow.com/questions/13039530/unable-to-call-firefox-from-selenium-in-python-on-aws-机器可能会有所帮助。 –

谢谢Priyank ..我检查了一个，但它不是我有同样的问题。我结束了使用另一个安装firefox并指向我的PATH env变量。 –

因为问题似乎与使用共享对象

WebDriverException: Message: "The browser appears to have exited before we could connect. The output was: XPCOMGlueLoad error for file /usr/bin/libxpcom.so:\n/usr/bin/libxpcom.so: cannot open shared object file: No such file or directory\nCouldn't load XPCOM.\n"

我最后不得不火狐的新安装做（我注意到以前的版本太旧，我没有权限升级它），指着我的PATH变量使用它：

setenv PATH /path/to/new/firefox/:$PATH
