So I followed wheatley's tuts on installing polymer.
I had  bower installed already(when i used angular with flask),  but i kept getting this error message

bower ESUDO         Cannot be run with sudo

Additional error details:
Since bower is a user command, there is no need to execute it with superuser permissions.
If you're having permission errors when using bower without sudo, please spend a few minutes learning more about how your system should work and make any necessary repairs.

ok thing is just saying we can't install it as root...not to worry, just add --allow-root to the end of the install command and that should do the trick.

bower install --save Polymer/polymer --allow-root
