node.js - NPM throw err 491 -


i have installed node hence run node -v , npm -v confirm have been installed. node -v returning version of node expected, npm -v throws bellow error. can issue?

module.js:491     throw err; ^  error: cannot find module '../lib/utils/unsupported.js'     @ function.module._resolvefilename (module.js:489:15)     @ function.module._load (module.js:439:25)     @ module.require (module.js:517:17)     @ require (internal/module.js:11:18)     @ /usr/local/lib/node_modules/npm/bin/npm-cli.js:19:21     @ object.<anonymous> (/usr/local/lib/node_modules/npm/bin/npm- cli.js:92:3)     @ module._compile (module.js:573:30)     @ object.module._extensions..js (module.js:584:10)     @ module.load (module.js:507:32)     @ trymoduleload (module.js:470:12)`

it might permissions problem, delete local/lib/node_modules folder , reinstall node. further info, might wanna check out error resolved on npm's github discussion.
