Unable to rpm run build

[ximbal]

I am trying to install ansijet, but in the last command (npm run build) I get an error message like this:

npm ERR! Linux 4.2.0-36-generic npm ERR! argv "node" "/usr/local/bin/npm" "run" "build" npm ERR! node v0.12.14 npm ERR! npm v3.9.2 npm ERR! code ELIFECYCLE npm ERR! [email protected] build: node --harmonywhich gulpbuild npm ERR! Exit status 1 npm ERR! npm ERR! Failed at the [email protected] build script 'node --harmony which gulp build'. npm ERR! Make sure you have the latest version of node.js and npm installed. npm ERR! If you do, this is most likely a problem with the ansijet package, npm ERR! not with npm itself. npm ERR! Tell the author that this fails on your system: npm ERR! node --harmony which gulp build npm ERR! You can get information on how to open an issue for this project with: npm ERR! npm bugs ansijet npm ERR! Or if that isn't available, you can get their info via: npm ERR! npm owner ls ansijet npm ERR! There is likely additional logging output above.

Any ideas? am I missing something?

node -v ----> v0.12.14
npm -v ----.> 3.9.2

Found a problem with GULP, this solves it

npm uninstall gulp npm install gulp -g npm install
