问题
I'm using a Macbook with the latest macOS (10.12.3), and I installed Homebrew by running:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
After that I installed node:
brew install node
And tried to upgrade it:
> brew upgrade node
> Error: node 7.8.0 already installed
I got an error saying the version 7.8.0 is already installed, that was expected since I had just installed the most recent version.
Problem: on the terminal I ran:
> node --version
> v4.4.5
and got back an old version that apparently was already installed. Also, when I install some new package through npm I get a warning saying the package requires an newer version of node.
Question: I seem to have both versions of node installed on my mac, how can I use the most current one? And how can I uninstall all other older node versions?
Thank you very much for your help!

My problem was solved following @theWanderer4865 suggestions in the comments.
First, I uninstalled the node version I had installed through brew: in the terminal I executed:
> brew cleanup
> brew uninstall node
Second, I removed all other node versions I had installed by running:
> rm -rf /usr/local/{lib/node{,/.npm,_modules},bin,share/man}/{npm*,node*,man1/node*}
Third, install node again using nvm:
> nvm install node

- brew install node
- brew upgrade node
- node -v
- sudo n latest
- node -v
1st step will install node using homebrew then you need to upgrade node using homebrew as in step 2 mentioned above , after then when you check node version you'll see latest node already installed but still works on older version, then finally when you run step 4 cmd it will install the latest node and if you check now this will show you the latest node version and ya you are ready to go now . This worked for me

I had a similar problem, and the Salome answer fixed it, but, when I opened a new shell, it reverted to an older version of node. If I typed node list I found I still had a number of versions, despite following Salome's instructions to remove all the old versions.
I could fix it by typing nvm use v7.8.0 , but that does not work for a new shell. I was able to fix it permanently following this SO answer
nvm alias default 7.8.0
