What happened for me was a naming conflict with old versions of node, so that the newer versions were ignored that I attempted to install. I would be informed I had the latest version of node, and npm, but this was obscured by the old version. To fix it, I had to completely uninstall it using the following:

sudo apt-get remove --purge node
