node.js - "npm install" not doing anything despite there being a package.json -

i'm not sure if because of upgrading npm or node, "npm install" working along till upgrade, , after struggling issue, decided reverted using nodejs v4.2.6 , npm v2.14.18 - still though, hasn't resolved issue. when removing node_modules folder , running "npm install", nothing can seen below:

this package.json
