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
The article on installing and using polymer is on http://www.weboverflow.me/2015/02/setting-polymer/
