PostgreSQL gem for rails won't install, even when both home brew and app are installed
At the end of the day it was:
ARCHFLAGS="-arch x86_64" bundle install
that worked for me.
reason being:
by default it tries to compile a universal binary, which apparently fails... so that environment variable makes it only compile the x86 version which is all you need
you can add this line to your
~/.profile
or similar:export ARCHFLAGS="-arch x86_64"
For further reading see: This README for OSX
Make sure Postgres is installed on your computer first
for Ubuntu systems: sudo apt-get install libpq-devon RHEL systems: yum install postgresql-develfor Mac: brew install postgresql
Then run bundle install
