Answer 1

nstore usess ‘pattern’ package from NPM.
look at “dependencies”:

https://github.com/creationix/nstore/blob/master/package.json

It should install with nstore (if you used npm install nstore)
If you checkout project from github you have to do:

npm install pattern

npm install step

and that’s it.
