Failed to run BS4

[Chen Lenorld]

Hi 

I have installed BS4 successfully but when I run it on IDLE, it shows: 

Traceback (most recent call last):

  File "<pyshell#3>", line 1, in <module>

    from bs4 import BeautifulSoup

  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/beautifulsoup4-4.6.0-py3.6.egg/bs4/__init__.py", line 35, in <module>

    from .builder import builder_registry, ParserRejectedMarkup

zipimport.ZipImportError: bad local file header: '/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/beautifulsoup4-4.6.0-py3.6.egg'

Can someone please help me to have a look? 

Thanks.
