Once installed, `n` caches Node.js versions in subdirectory `n/versions` of the directory specified in environment variable `N_PREFIX`, which defaults to `/usr/local`; and the _active_ Node.js version is installed under `N_PREFIX`.
To avoid requiring `sudo` for `n` and `npm` global installs, it is suggested you either install to your home directory using `N_PREFIX`, or take ownership of the system directories:
# make cache folder (if missing) and take ownership
sudo mkdir -p /usr/local/n
sudo chown -R $(whoami) /usr/local/n
# take ownership of node install destination folders
# take ownership of Node.js install destination folders
sudo chown -R $(whoami) /usr/local/bin /usr/local/lib /usr/local/include /usr/local/share
