Acts-as-taggable-on migration (table)

Hello,

I just installed acts-as-taggable-on gem (available here:
GitHub - mbleigh/acts-as-taggable-on: A tagging plugin for Rails applications that allows for custom tagging along dynamic contexts.) but it seems like it
didnt install the migration table generator.

When I do:

script/generate acts_as_taggable_on_migration

I get error: Couldn’t find ‘acts_as_taggable’ generator

I have also noticed that other people have the same problems with
current version but there is no updated available (or perhaps I’m doing
something wrong).

Could someone please share the migration for the gem so that I can
create tables without generator?

And another question: Is there any better ‘taggable’ plugin/gem for ROR
available?

Thanks for help!
