I have a working postgresql database. My database.yml file is using “postgresql” for the adapter. I have the pg gem installed (0.12.2). But trying to run my Sinatra app, Passenger gives me this error message: Please install the postgresql adapter: ‘gem install activerecord-postgresql-adapter’ (Could not find pg (~> 0.11) amongst blah blah blah……..
Any ideas on why it can’t find my pg gem?
Problem solved. I had installed rvm and ruby under my user, but used “sudo” to install passenger, so passenger was looking in the wrong place for my gems. Reinstalled without sudo and now it works! Hope this helps someone else.
