Error in Bundler with PostgreSQL and Rails3

Hi there,

I’m trying to get up and running with PostgreSQL 8.4 and the Rails 3
beta. I’m running on Ruby 1.8.7 via RVM and have installed the ‘pg’
gem. While I’ve been able to get the pg gem to successfully build,
whenever I create a new rails app, tell it to use Postgres, and execute
‘rails server’ I get the following error:

jury$ rails server
/Users/jury/.rvm/gems/ruby-1.8.7-p249/gems/pg-0.8.0/lib/pg.bundle:
dlsym(0x1026ef640, Init_pg): symbol not found -

from /Volumes/Khronos/jury/Documents/rails3/postApp/script/rails:10

I’m guessing this is either an error in bundler or ruby-pg, but would
appreciate any pointers if anyone has run into this before and worked
around it.

For that matter, has anyone out there successfully got the Rails 3 beta
and Postgres working well together? If so, I’d love to know what you’ve
done.

Thanks in advance!

I just try and all are working good under Ruby 1.8.7 MRI… (I did’nt
try RVM…)

I did’nt any special thing, I just install pg gem and run:

rails xxx -d postgresql
cd xxx
I have modify config/database.yml adding => host: localhost and setting
user / password
rails generate scaffold user name:string published:boolean
rake db:create
rake db:migrate
rails server

=> http://localhost:3000/users

CRUD operations are all working good

Hope this helps…

Wait a moment…

Do you have removed the old versions of bundler gem ? (I think that is
very important to have only the last version installed !!!)

So looks like this is an issue with the PostgreSQL install that I
happened to snag. I just finished blowing everything away and
reinstalling it all from MacPorts and it’s working like a charm.

Huge thanks for your hep, Gianluca!
