So I think /home/ubuntu/nvm is not correct any more and it actually needs to be /opt/circleci/nodejs/
However, as I specify my node version using the “v6” shorthand, and the directory that gets created is currently 6.9.3, I have no way of referencing that directory name inside my circle.yml file.
It would be great if I could put something in my circle.yml file that uses the installed directory name for node so that I can cache global npm packages.
