I was getting similar error in Node(v8.1.0) and NPM(5.0.3) Version in Windows 10. Followed following steps to fix this issue. a) Uninstalled npm & Node.js completly. b) Delete "npm" & "npm-cache" folders from "C:\Users\\AppData\Roaming" location. c) Install latest node version through ".msi" d) from node command prompt run "npm i -g npm" e) move to your project location and run "npm install" it should work.
