使用splinter来浏览网页，无法获取浏览器

Question

起初我尝试了标准“来自splinter import Browser”，但是我遇到了以下错误：

    from splinter import browser
ImportError: No module named 'splinter'

现在，我通过git安装它，并确保创建了dist-packages。我已经尝试过python 2.7和3.现在，我正在使用以下内容：

#!/usr/bin/env python2 (get errors when changing to 3 as well)

import splinter

def navigate_to(web_page, how_long):
    b = splinter.Browser()
    b.visit(web_page)

给出以下

    Traceback (most recent call last):
  File "./hw", line 30, in <module>
    navigate_to(platform_int, 60)
  File "./hw", line 23, in navigate_to
    b = splinter.Browser()
  File "build/bdist.linux-x86_64/egg/splinter/browser.py", line 63, in Browser
  File "build/bdist.linux-x86_64/egg/splinter/driver/webdriver/firefox.py", line 49, in __init__

    self.service.start()

  File "/usr/lib/python2.7/subprocess.py", line 390, in __init__
    errread, errwrite)
  File "/usr/lib/python2.7/subprocess.py", line 1024, in _execute_child
    raise child_exception
OSError: [Errno 8] Exec format error
