Question

I was doing an exercise from the ruby on rails tutorial which involves installing postgresql. Following the instructions from a rails cast linked in the tutorial, I did

brew install postgresql

This errored. On searching online, found a thread on a forum which suggested doing

brew unlink ossp-uuid && brew link ossp_uuid

I don’t know what this is achieving. The command failed (I think the first part succeeded). The error:

Could not symlink file: /usr/local/Cellar/ossp-uuid/1.6.2/share/man/man3/uuid.3
/usr/local/share/man/man3 is not writable. You should change its permissions.

What is this about? Why do we need to create this symbolic link?

Thanks in advance!

Answer 1

You likely need to use sudo before the command.

Alternatively, postgres can be installed from an installer from their site: Mac OS X installer
