So, I got a small site started in node.js (my first one) using Express. Pretty happy with it, until I tried to deploy to Heroku and found that I had 0.4.9 installed and they only support 0.4.7.
Is uninstalling 0.4.9 and installing 0.4.7 my only option, or is there a way to do a side-by-side on the two?
You can override the version of node.js and npm by customizing the Heroku build pack:
