Splinter Selenium Phantomjs驅動程序在實例化時失敗

Question

我正在嘗試使用Python + Splinter + Selenium + PhantomJS進行基本測試，但我無法啟動phantomjs瀏覽器。 （Chrome和Firefox驅動程序工作正常。）當我運行時：

from splinter import Browser

b = Browser('phantomjs')

我收到錯誤：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Python/2.7/site-packages/splinter/browser.py", line 63, in Browser
    return driver(*args, **kwargs)

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

另外，當我跑：

from selenium import webdriver

d = webdriver.PhantomJS()

我得到了基本相同的錯誤。

看起來PhantomJS正在使用遠程驅動程序連接到遠程服務器，但是分裂器沒有啟動用於PhantomJS連接的selenium（？）服務器。 我不介意進入splinter（？）的源代碼並更改一些東西以使其工作。 但是，我無法確定解決這個問題的方法。

或者，我是否需要手動啟動服務器以便PhantomJS連接？

（作為參考，Ruby + Cucumber + Capybara + Poltergeist在我的盒子上工作正常。）這是我的軟件的配置。

$ python --version
Python 2.7.10

$ pip show splinter | grep Version
Metadata-Version: 1.1
Version: 0.7.3

$ pip show selenium | grep Version
Metadata-Version: 2.0
Version: 2.47.3

$ phantomjs -v
2.0.0

只是想分享phantomjs + splinter與我的機器下面的配置很好地工作：

~ $ python --version
Python 2.7.11

~ $ pip show splinter | grep Version
Metadata-Version: 1.1
Version: 0.7.3

~ $ pip show selenium | grep Version
Metadata-Version: 2.0
Version: 2.47.3

~ $ phantomjs -v
2.0.0

~ $ sw_vers
ProductName:    Mac OS X
ProductVersion: 10.11
BuildVersion:   15A284

我有同樣的錯誤。 然后我檢查我的/ etc / hosts並刪除不必要的localhost別名。 所有的工作。 檢查你的/ etc / hosts
