Workaround to get NodeJs 14 to work with Mac Silicon. Apple provides Rosetta, a translation app that allows applications that are built for Intel Chip (or previous generation Mac) to run under Apple Silicon.
/usr/sbin/softwareupdate --install-rosetta --agree-to-license
# Switch to i386
arch -x86_64 zsh
# Confirm (should print "i386"
arch
# Install node
nvm install 14
