I''ve trying to use the postgres-pr gem on CentOS/Ruby 1.9.2. When I attempt to run Webrick (or rake update), I get an error saying that it cannot find the gem "postgres." I''m not sure why, because nowhere in my Gemfile or database.yml do I refer to anything called "posgres." Any suggestions? -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Postgres is confusing (to me). I install "pg (0.10.0)" and that is working for me. I''m currently toying with Rails 3 using Ruby 1.9.2 but I''ve done lots of Ruby 2 using Ruby 1.8 and 1.9.1. If you use the --database=postgresql option when you create your project, it will have this at the top: # PostgreSQL. Versions 7.4 and 8.x are supported. # # Install the pg driver: # gem install pg # On Mac OS X with macports: # gem install pg -- --with-pg-config=/opt/local/lib/postgresql84/bin/pg_config # On Windows: # gem install pg # Choose the win32 build. # Install PostgreSQL and put its /bin directory on your path.

I got the same error using the pr gem... Strange. There is some dependency somewhere that I can''t find.

Is it possible that when you do "gem" you are using a different copy
of
Ruby than if you run your rails application?
There is at least one requirement here:
activerecord-2.3.5/lib/active_record/connection_adapters/postgresql_adapter.rb
(replace 2.3.5 with your flavor of Rails)
begin
require_library_or_gem ''pg''
rescue LoadError => e
begin
require_library_or_gem ''postgres''
class PGresult
alias_method :nfields, :num_fields unless
self.method_defined?(:nfields)
alias_method :ntuples, :num_tuples unless
self.method_defined?(:ntuples)
alias_method :ftype, :type unless self.method_defined?(:ftype)
alias_method :cmd_tuples, :cmdtuples unless
self.method_defined?(:cmd_tuples)
end
rescue LoadError
raise e
end
end

Possible... Thanks for the suggestions. I''ll have to try that out.
