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

If during the installation of the gem the pq installation is not in path so it could not be found by the gem. Than the gem would not work correct.

• Check the path (try to start psql from commandline).
• uninstall the pg-gem: gem unistall pg
• and reinstall it: bundle install or gem install pg
