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

Answer 1

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

• div-cowboy: But isn't slightly wreckless to install things by overriding all permissions or is it common?
• kjsmita6: @user3236637 it isn't really "overriding" since root access is required to install things globally.

Answer 2

bash sudo rm -rf /usr/local/bin/npm /usr/local/share/man/man1/node* /usr/local/lib/dtrace/node.d ~/.npm ~/.node-gyp

this should work
