In the past, I''ve used mysql with rails without problem. I need to work
with postgresql, but I''m having trouble getting it working.
I''ve seen
conflicting reports on what gems are needed. My latest install was
sudo gem install postgres --
--with-pgsql-include-dir=/Library/PostgreSQL8/include
--with-pgsql-lib-dir=/Library/PostgreSQL8/lib
(note: I did this blindly. It''s about my 6th try to get proper gems in
place)
I''m running Rails 2.3.8 and PostgreSQL 8.4.2
My .yml configuration is
development:
adapter: postgresql
database: movies
username: michael2
port: 5432
allow_concurrency: true
encoding: SQL_ASCII
When I try to do a test connect with rake db:migrate, I get the
following:
rake db:migrate --trace
(in /oldhome/michael/projects/movies)
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
rake aborted!
syntax error on line 3, col 9: ` adapter: postgresql''
/usr/lib/ruby/1.8/yaml.rb:133:in `load''
/usr/lib/ruby/1.8/yaml.rb:133:in `load''
---------
Can anyone offer some help? Thanks much

Thanks muchRails is failing on a syntax error in your database.yml file. It has nothing to do with PostgreSQL at this point.

I then executed the following: irb irb(main):001:0> require ''pg'' => true In other words, it is still finding ''pg'' after uninstalling the gem. That''s likely the problem.
