I think I had remnants of other installations of node/npm/nvm from my previous attempts at installing using the official instructions (which failed). To remove them I did:

rm -rf /usr/lib/node_modules
rm -rf .cncjs*
rm -rf .nvm
rm -rf .npm

Then I re-ran this install script and it worked wonderfully. 👍
