ImportError: cannot import name cached_property
Question: I am trying to set up Tipfy extensions on a Python/Google App Engine project
that I've been brought in on. I have followed all the instructions for running
bootstrap.py and then bin/buildout. Everything seems to have worked but now
when I try to import tipfy.ext.auth, I get this error:

    
    
    File "C:\{project}\app\lib\dist\tipfy\ext\auth\__init__.py", line 15, in <module>
        from tipfy import abort, cached_property, import_string, redirect
    ImportError: cannot import name cached_property
    

I'm a bit lost now and don't really know where to even look for the solution
to this as I am, admittedly, very new to both Python and GAE. Any help or
direction on how to get this extension working would be greatly appreciated.


Answer: Potential solution here:

tl;dr: Remove that import and import from werkzeug instead.
