Selenium-3.0とPython 2.7がインストールされていますがモジュールのエラーはありません

Question

私はここで見つかったすべてを試しました。私はオプションを使い果たしました。なにが問題ですか？

Praysons-MacBook-Pro:pyChrome praysondaniel$ pip install -U selenium 
Requirement already up-to-date: selenium in /usr/local/lib/python2.7/site-packages/selenium-3.0.0b3-py2.7.egg 

Praysons-MacBook-Pro:pyChrome praysondaniel$ python 
Python 2.7.10 (v2.7.10:15c95b7d81dc, May 23 2015, 09:33:12)

>>> from selenium import webdriver 
Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
ImportError: No module named selenium

私はこのImportError: No module named 'selenium'を含む他のすべての提案を試しました。

>>> import sys; sys.path
