==> Pouring sphinx-doc-1.8.1.mojave.bottle.tar.gz
==> Caveats
sphinx-doc is keg-only, which means it was not symlinked into /usr/local,
because this formula is mainly used internally by other formulae.
Users are advised to use `pip` to install sphinx-doc.

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

Warning: Building python from source:
  The bottle needs the Apple Command Line Tools to be installed.
  You can install them, if desired, with:
    xcode-select --install
