For those who are looking for /usr/local/sbin is not writable error:

UPDATE: It could be /usr/local/someOtherFolderName e.g /usr/local/include. You just need to create that folder with:

• sudo mkdir someOtherFolderName

First create the sbin folder, note that this requires sudo privileges

• cd /usr/local

• sudo mkdir sbin

• sudo chown -R $(whoami) $(brew --prefix)/*

• brew link yourPackageName
