running npm install after php artisan laracogs:bootstrap stuck at node scripts/install.js

[swanand09]

When I run npm install it stuck at node scripts/install.js. When I re run it I got this:
npm WARN optional Skipping failed optional dependency /chokidar/fsevents: npm WARN notsup Not compatible with your operating system or architecture: fsevents@1.0.14 npm WARN optional Skipping failed optional dependency /gulp-watch/chokidar/fsevents: npm WARN notsup Not compatible with your operating system or architecture: fsevents@1.0.14

and then run gulp
[10:59:42] Using gulpfile /var/www/html/testlaracog/gulpfile.js [10:59:42] Starting 'default'... [10:59:42] Starting 'sass'... Bus error (core dumped)

Can anyone help?
Thanks

well I solved it by doing npm install npm which upgraded the version of npm to 3.10.5
