Uninstalling Node.js On a Mac

Question

So I installed Node.js by downloading the mac 0Sx package from their website, but now every time I try to run a command such as f$ grunt-cli -v I get the following error below. This path /usr/local/bin/npm also doesn't exist on my computer, and I don't know how to find node.js to unistall it, and then re-install it using homebrew. Let me know if I have left any info out.

-bash: grunt-cli: command not found

EACCES means you don't have root access. Reinstalling node/npm won't help. Like it says, try running it as admin:

sudo npm install -g grunt-cli

Or if you don't want to use sudo , install nvm (note nvm may not allow you to globally install on mac, but it does on ubuntu so it might work):

$ git clone https://github.com/creationix/nvm.git ~/.nvm && cd ~/.nvm && git checkout `git describe --abbrev=0 --tags`
$ ...
$ ~/.nvm/nvm.sh
$ ...
$ nvm install stable
$ ...
$ nvm use stable
$ npm install -g grunt-cli
