Error installing pg gem on osx

Question

I am on osx 10.6.7 trying to run bundle install on a new rails 3.0.7 app and it keeps failing when trying to build the pg gem. It keeps telling me that I have need the devel

Answer 1

I was stuck on my bundle install for 3 days. Tried Everything like adding env ARCHFLAGS="-arch x86_64" gem install pg -- --with-pg-config=/usr/local/Cellar/postgresql/9.3.5_1/bin/pg_config

I was able to see pg gem getting installed after this command but still it was not installing from bundle install, which was a pain because I dint know what to write in Gemfile except gem 'pg'

The thing which finally worked for me was to find that my pg_config was in /Library/PostgreSQL/9.3/bin/pg_config and by default the Gemfile bundle install looks in /usr/local/bin/pg_config

I just ran the following command and magic happened. bundle config build.pg --with-pg-config=/Library/PostgreSQL/9.3/bin/pg_config
