npm install -g bower (no need if you have installed bower)
bower install
bower prune
bower update
npm install -g gulp (no need if you have installed gulp)
gulp install

in a project directory

Remove .cache folder first, I guess that .cache folder created with different permissions, it happens when You play with sudo and etc.

So run this:

sudo rm -rf /home/caner/.cache

and after that run Your commands again
