==> Pouring node@10-10.15.3.mojave.bottle.tar.gz
==> Caveats
node@10 is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.

If you need to have node@10 first in your PATH run:
  echo 'export PATH="/usr/local/opt/node@10/bin:$PATH"' >> ~/.zshrc

For compilers to find node@10 you may need to set:
  export LDFLAGS="-L/usr/local/opt/node@10/lib"
  export CPPFLAGS="-I/usr/local/opt/node@10/include"
