An error occurred while installing pg (0.16.0), and Bundler cannot continue.
Make sure that `gem install pg -v '0.16.0'` succeeds before bundling.

==> Pouring postgresql-9.3.2.mountain_lion.bottle.tar.gz
==> Caveats
If builds of PostgreSQL 9 are failing and you have version 8.x installed,
you may need to remove the previous version first. See:
  https://github.com/Homebrew/homebrew/issues/issue/2510

To migrate existing data from a previous major version (pre-9.3) of PostgreSQL, see:
  http://www.postgresql.org/docs/9.3/static/upgrading.html

When installing the postgres gem, including ARCHFLAGS is recommended:
  ARCHFLAGS="-arch x86_64" gem install pg

To install gems without sudo, see the Homebrew wiki.

To have launchd start postgresql at login:
    ln -sfv /usr/local/opt/postgresql/*.plist ~/Library/LaunchAgents
Then to load postgresql now:
    launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
Or, if you don't want/need launchctl, you can just run:
    postgres -D /usr/local/var/postgres
Warning: Could not link postgresql. Unlinking...
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
You can try again using `brew link postgresql'

Possible conflicting files are:
Warning: Could not link postgresql. Unlinking...
Error: Permission denied - /usr/local/lib/pkgconfig

Not sure what else I can try - I have the Postgres app installed as well.

  • Regarding `brew install postgres`: Looks like permissions on `/usr/local` are not right. What do `brew doctor`, `ls -ld /usr/local` and `ls -ld /usr/local/lib` report? – Jimothy Jan 08 '14 at 22:24

  • **Always** explain how you installed PostgreSQL on your system. Is homebrew the only PostgreSQL install here, or is it an attempt you made to solve a problem by installing a second copy of PostgreSQL? – Craig Ringer Jan 09 '14 at 00:38

If you're using Postgress.app, you need to specify --with-pg-config when you install the Gem.

See this Q&A for details.

  • Yep. And installing another build of PostgreSQL instead is *not* the answer. The "flail around running random commands until it seems to work" school seems to be popular with a subset of the Rails crowd (lots of newbie programmers presumably) and creates pain like this question. Thanks for a clear "the right way" kind of answer. – Craig Ringer Jan 09 '14 at 00:39
