Answer 1

Not sure about grunt etc, but to simply install any node library, do:

            apt-get install npm 

from the command line, thereafter any node module should be installed with:

            npm install MODULE_NAME

e.g.:

            npm install spdx-license-ids

or to install it globally so node can find it anywhere on your system (not always such a briliiant idea, but anyways), use the global -g flag:

           npm install -g MODULE_NAME 

Those extraneous tools can trip you up sometimes - grunt, yeoman, etc
