Ruby/PgSQL error on Rails start : cannot load such file — pg_ext (LoadError)

Question

I\'m new to Ruby (coming from a Java background) and was given access to a RoR project from a Git repository. I was able to get Ruby built with rbenv and Postgres installed

Answer 1

Issue also appears in Fedora 17.

Uninstall "pg" gem:

gem uninstall pg

Run bundle (assuming Gemfile contains "pg" gem):

bundle
