GAE SDK 1.9.5 and an InvalidCertificateException
Question: Trying to import testbed from GAE SDK 1.95 with Python2.7.8 on osX Maverics
10.9.5 and I'm getting a InvalidCertificateException error.

    
    
        from google.appengine.ext import testbed   
      File "/usr/local/google_appengine/google/appengine/ext/testbed/__init__.py", line 120, in <module>  
        from google.appengine.api import urlfetch_stub   
      File "/usr/local/google_appengine/google/appengine/api/urlfetch_stub.py", line 34, in <module>  
        _fancy_urllib_InvalidCertException = fancy_urllib.InvalidCertificateException  
    AttributeError: 'module' object has no attribute 'InvalidCertificateException'   
    

I looked at the fancy_url module and the InvalidCertificateException class is
there, so I don't understand why it's not importing.

Apparently others have had the same error, so I attempt to correct it by
deleting: **urlfetch_cacerts.txt** AND **cacerts.txt** from:

    
    
    GoogleAppEngineLauncher/Contents/Resources/GoogleAppEngineDefault.bundle/Content‌​s/Resources/google_appengine/lib/cacerts/
    


Answer: Apparently the GAE installer creates a nested directory, this was fixed by
copying the contents in:

    
    
    cd /usr/local/google_appengine/lib
    cp fancy_urllib/fancy_urllib/__init__.py fancy_urllib/__init__.py 
    

This is how the module is incorrectly structured, it looks like these 2
**init**.py files are duplicate:

    
    
    /usr/local/google_appengine/lib/fancy_urllib/__init__.py   # this file is empty
    /usr/local/google_appengine/lib/fancy_urllib/fancy_urllib/__init__.py # this file contains the functions.
    

FIXED THE ERROR
