Installing Homebrew on a Mac with NPM already installed

Question

I am trying to fix my npm permissions.

On this page, under Option 3, it says:

If you're doing a fresh install of node on Mac OS you can avoid this problem altogether by using the Homebrew package manager...

If I'm doing a fresh install? Does it not work if I already have node installed? I would be willing to reinstall node if I could find the proper way to uninstall it.

Please provide instructions how to install homebrew on a Mac with existing npm and node already installed.

Mac OSX v10.10.5 Yosemite

Sure thing:

rm -rf /usr/local/Cellar /usr/local/.git && brew cleanup

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/ \install/master/install)"

brew doctor

That first command is to cleanup any previous versions of homebrew already installed. Hope this helps - had to do something similar recently as well.
