nvm_install_latest_npm: avoid unbound variable
# Node Version Manager
# Implemented as a POSIX-compliant function
# Should work on sh, dash, bash, ksh, zsh
# To use source this file from your bash profile
#
# Implemented by Tim Caswell <tim@creationix.com>
# with much bash help from Matthew Ranney
# "local" warning, quote expansion warning, sed warning, `local` warning
# shellcheck disable=SC2039,SC2016,SC2001,SC3043
