[node.js] How to change to an older version of Node.js

For some reason Brew installs node 5 into a separate directory called node5.

The steps I took to get back to version 5 were: (You will need to look up standard brew installation/uninstallation, but otherwise this process is more straightforward than it looks.)

  1. Install node5 using Brew standard installation, BUT don't brew link, yet.
  2. Uninstall all other versions of node using brew unlink node and brew uninstall node. You might need to use --force to remove one of the versions.
  3. Find the cellar folder on your computer
  4. Delete the node folder in the cellar.
  5. Rename the node5 folder to node.
  6. Then, brew link node

You should be all set with node 5.
