Answer 1

what do you mean by While installing grunt? Installing the grunt-cli tools or the grunt-runner in your project?

since 4.0 grunt is split into 2 modules:

• grunt-cli
• grunt

grunt-cli needs to be installed globally, and only 1 time:

$ npm install grunt-cli -g

grunt needs to be installed locally in every project where you want to use grunt and grunt-plugins:

$ npm install grunt

---

updating npm:

the crazy stuff about npm is, that you can even update npm via npm:

$ npm update npm -g

the current npm version is 2.1.9, so maybe this solves your problem.

hint: use nvm vor node.js version management. this solves multiple problems:

1. easy version switching
2. you don't need sudo for global packages
