npm run prod fails

[BitLox]

Hi, nice template.

npm run dev works fine, but when I want to shift to production serving the site I get an error:

player1@MacBook krypton % npm run prod

> krypton@4.0.0 prod /Users/player1/Documents/krypton
> gulp prod

[22:33:11] Using gulpfile ~/Documents/krypton/gulpfile.js
[22:33:11] Task never defined: prod
[22:33:11] To list available tasks, try running: gulp --tasks

npm ERR! 
npm ERR! Failed at the krypton@4.0.0 prod script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
