No local gulp install found even after installing npm install -g gulp

I tried to install gulp by npm install -g gulp The output seems to be something like this. (i have skipped some logs) npm http 304 https://registry.npmjs.org/string_decoder npm http 304 https://registry.npmjs.org/lodash._htmlescapes /usr/bin/gulp -> /usr/lib/node_modules/gulp/bin/gulp.js gulp@3.6.2 /usr/lib/node_modules/gulp ├── tildify@0.2.0 ├── pretty-hrtime@0.2.1 ├── deprecated@0.0.1 ├── archy@0.0.2 ├── semver@2.2.1 ├── chalk@0.4.0 (has-color@0.1.7, ansi-styles@1.0.0, strip-ansi@0.1.1) ├── orchestrator@0.3.3 (sequencify@0.0.7) ├── liftoff@0.9.8 (extend@1.2.1, minimist@0.0.8, resolve@0.6.3, findup-sync@0.1.3) ├── vinyl-fs@0.1.4 (graceful-fs@2.0.3, map-stream@0.1.0, mkdirp@0.3.5, vinyl@0.2.3, glob-stream@3.1.9, glob-watcher@0.0.6) └── gulp-util@2.2.14 (lodash._reinterpolate@2.4.1, dateformat@1.0.7-1.2.3, minimist@0.0.8, vinyl@0.2.3, multipipe@0.0.2, through2@0.4.1, lodash.template@2.4.1) In the above script i can see a line /usr/bin/gulp -> /usr/lib/node_modules/gulp/bin/gulp.js which i guess is making a simulink in bin folder. So i should be getting gulp globally but i get the this error. No local gulp install found in /var/www/ksapp Any idea why i am getting this error. Thanks
