NPM Install error

[drawcard]

I am hitting the following error when attempting to install via NPM, I think package.json needs updating to reflect new standards.

$ npm install --save jquery-fatNav

Workaround: npm install --save https://github.com/Glitchbone/jquery-fatNav

yarn seems to work too: yarn add Glitchbone/jquery-fatNav
