1. brew install nodejs
    3. icu4c is keg-only, which means it was not symlinked into /usr/local,
    4. because macOS provides libicucore.dylib (but nothing else).
    6. If you need to have icu4c first in your PATH run:
    7.   echo 'export PATH="/usr/local/opt/icu4c/bin:$PATH"' >> ~/.zshrc
    8.   echo 'export PATH="/usr/local/opt/icu4c/sbin:$PATH"' >> ~/.zshrc
    10. For compilers to find icu4c you may need to set:
    11.   export LDFLAGS="-L/usr/local/opt/icu4c/lib"
    12.   export CPPFLAGS="-I/usr/local/opt/icu4c/include"
    14. ==> node
    15. Bash completion has been installed to:
    16.   /usr/local/etc/bash_completion.d
