问题

I am using capistrano and get this error message:

Please install the pg adapter: `gem install activerecord-pg-adapter` (cannot load such file -- active_record/connection_adapters/pg_adapter)

I have removed the gem 'pg' from my Gemfile and bundle installd . I don't see the pg gem in my Gemfile.lock. I have also changed my production db to a sqlite3 adapter. Why is Rails 3.2 / Capistrano / Bundler asking for this? I'm not using it and not in Gemfile.lock and how do I resolve it? I am using ubuntu 12.04 on server that this is happening on.

thx in advance

Also, when I run what it tells me to run, I get:

deploy@oahu:~$ gem install activerecord-pg-adapter
ERROR:  Could not find a valid gem 'activerecord-pg-adapter' (>= 0) in any repository

Check your database.yml. You probably have an entry in it called pg-adapter, when the correct adapter for Postgres is postgresql. If you remove or replace that, this should work.
