Hmmm. Perhaps I missed something, but Sequel::Migrator is not
defined:
>> require 'sequel'
=> true
>> DB = Sequel.connect(:adapter => 'mysql', :user => 'root', :database =>
>> 'castle_gameserver')
=> #<Sequel::MySQL::Database: "mysql:root@/castle_gameserver">
>> Sequel::Migrator.apply(DB, '/myproject/db/migrations/')
NameError: uninitialized constant Sequel::Migrator
from (irb):3
I thought maybe you forgot a middle module (like maybe
Sequel::SQL::Migrator or something), so I checked the rdoc
http://sequel.rubyforge.org/rdoc/index.html
And searched for "Migrator". Nothing. What am I doing wrong here?
On a different note, since I'm not good at letting things go:
I tried setting RUBYLIB as you show above, but now I get a new error:
$ export RUBYLIB=/System/Library/Frameworks/Ruby.framework/Versions/
1.8/usr/lib/ruby/1.8/
$ sequel mysql://localhost/castle_gameserver?user=root
/usr/bin/sequel:19: undefined method `bin_path' for Gem:Module
(NoMethodError)
What gives?
