python – Splinter Selenium Phantomjs驱动程序在实例化时失败

from splinter import Browser

b = Browser('phantomjs')

我收到错误：

    raise URLError(err)
urllib2.URLError: <urlopen error [Errno 8] nodename nor servname provided,or not known>

另外,当我跑：

from selenium import webdriver

d = webdriver.PhantomJS()

我得到了基本相同的错误.

看起来PhantomJS正在使用远程驱动程序连接到远程服务器,但是分裂器没有启动用于PhantomJS连接的selenium(？)服务器.我不介意进入splinter(？)的源代码并更改一些东西以使其工作.但是,我无法确定解决这个问题的方法.

或者,我是否需要手动启动服务器以便PhantomJS连接？

(作为参考,Ruby Cucumber Capybara Poltergeist在我的盒子上工作正常.)
这是我的软件配置.
