I cannot find any instructions for correctly uninstalling io.js from Mac OS X. The only guide i can find online is here, but the directory it mentions for io.js doesn't seem to exist on my computer, or I don't know where to look: https://www.binarysludge.com/2015/01/14/how-to-uninstall-io-js-or-io-js-and-node-js-together/
I think I've got a real mess with node/npm/nvm/io.js, and don't think i can start working out how to set everything up correctly unless i can figure out how to get rid of io.js.
I installed io.js using the package from the website for Mac OS X.
