On this post I have added some of notes to Install Protobuf on macOS High Sierra version 10.13.6
esumits-MacBook-Pro:~ esumit$ brew install protobuf

==> Caveats
This formula is keg-only, which means it was not symlinked into /usr/local,
because macOS provides an older sqlite3.
If you need to have this software first in your PATH run:
echo ‘export PATH=”/usr/local/opt/sqlite/bin:$PATH”‘ >> ~/.bash_profile
For compilers to find this software you may need to set:
LDFLAGS: -L/usr/local/opt/sqlite/lib
CPPFLAGS: -I/usr/local/opt/sqlite/include
For pkg-config to find this software you may need to set:
PKG_CONFIG_PATH: /usr/local/opt/sqlite/lib/pkgconfig

Pip and setuptools have been installed. To update them
pip install –upgrade pip setuptools
You can install Python packages with
pip install <package>
They will install into the site-package directory
/usr/local/lib/python2.7/site-packages
