rake db:migrate postgreSQL

I finally got the gem pg to install. Now when I go to migrate the database I get the following:

$ rake db:migrate
(in c:/rubyDev/bsbaslic)

Does anybody have any ideas as to what it is looking for? I have a pg_ext.so file in the same directory as pg.rb.

Windows programs cannot load .so files - they load .dll files instead. You need a build of pg compiled for Windows, or you need to be running Ruby from within a Linuxy environment such as msys or cygwin.

The problem is in your version of pg gem. There is a special version for windows pg 0.9.0. In order to have it workingon windows:

1. uninstall the current pg 0.10.0

2. install pg as follows: gem install pg --version=0.9.0 -- --with-pg-config=/short/path/to/postresql/bin (To get short path you can simply change directory to PostgrSQL bin and then type command in cmd, it will automaticaly change path to a short verison)

3. Then edit your project Gemfile in order to use correct pg gem version (0.9.0)

And that's it.

Good Luck
