Following the instructions here:

# list latest stable versions: $ nodenv install -l # list all local versions: $ nodenv install -L # install a Node version: $ nodenv install 16.13.2 

The first and last commands work as described, but the middle one does not seem to be recognized. nodenv versions seems to be the correct command for this, but I am not sure if that should be substituted in or if nodenv install is supposed to have such a command.
