Thanks gusdrawn for raising this issue. I verified your findings with a fresh install. https://github.com/mklement0/n-install states: Before you can use n and any installed Node.js versions, you must open a new terminal tab/window or reload your shell initialization file. I got that wrong in the original configuration script. However the suggested solution mentioned on the website above does NOT work either:

set -i          # turn on interactive mode
. ~/.bashrc     # reload (source) the initialization file
set +i          # turn interactive mode back off

The workaround that I came up with to execute a separate shell script that installs node. I do not claim that this is elegant but it works. If you have a more elegant solution please drop me a line.
