The first issue I see is that you should put the RAILS_ENV declaration at the beginning of your command as this sets that variable for the life of the command.

RAILS_ENV=production bundle exec rails generate admin_interface:setup

This could be the root cause entirely. (Also note the use of bundle exec to be sure that the gemset specified in the Gemfile is properly loaded)

If you want to set it for the shell, run:

export RAILS_ENV=production

So you don't have to manually set it for every command.

The second possibility is that the database adapter is not properly configured. If this is a Ruby on Rails app, the database adapter is defined in config/database.yml. If not specified, it may be defaulting to sqlite3. Make sure you have a properly setup database.yml file.

  adapter: postgresql
  database: rails4_stack
  username: myusername
  password: mypassword
  pool: 5
  timeout: 5000
  encoding: utf8
  reconnect: false
