You need to try this commands line by line:
npm cache clean
npm install -g gulp bower
npm install
bower install
gulp & gulp watch
This commands do:
for cleaning a cache of npm
installs gulp bower globally
installs npm
installs bower
for mixing all js and css and watch on all changes of css & js
Hope this will helps you and fixed your issue!
