Estou tentando instalar especificamente o Node.js v6, o que está se mostrando confuso.

Em um novo MacBook executando o Sierra, executei:brew install node@6

Isso me deu:

Please note by default only English locale support is provided. If you need
full locale support you should either rebuild with full icu:
  `brew reinstall node --with-full-icu`
or add full icu data at runtime following:
  https://github.com/nodejs/node/wiki/Intl#using-and-customizing-the-small-icu-build

This formula is keg-only, which means it was not symlinked into /usr/local.

This is an alternate version of another formula.

If you need to have this software first in your PATH run:
  echo 'export PATH="/usr/local/opt/node@6/bin:$PATH"' >> ~/.zshrc

For compilers to find this software you may need to set:
    LDFLAGS:  -L/usr/local/opt/node@6/lib
    CPPFLAGS: -I/usr/local/opt/node@6/include


Bash completion has been installed to:
  /usr/local/etc/bash_completion.d
==> Summary
  /usr/local/Cellar/node@6/6.9.5: 3,891 files, 41.3M

Se eu correrwhich node, Eu recebonode not found. Se eu correrbrew link node, Eu receboError: No such keg: /usr/local/Cellar/node. Eu também corrisudo chown -R $USER /usr/local.

Como posso "vincular" o Node.js v6 para que outro software possa encontrá-lo? Eu corroecho 'export PATH="/usr/local/opt/node@6/bin:$PATH"' >> ~/.zshrc? Não quero executar nada de que não tenha certeza.
