I get the following error while running npm install on a fresh laravel 5.6 installation on windows 7 32 bit , npm version 5.7.1 , node v9.5.0

EDIT :

My Package.json file

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:

1. for cleaning a cache of npm

2. installs gulp bower globally

3. installs npm

4. installs bower

5. for mixing all js and css and watch on all changes of css & js

Hope this will helps you and fixed your issue!
