Can't install extensions, because no such table: extension_meta:

[Linutux]

When I do

rvm@localhost:path# git clone https://github.com/gerrit/radiant-drag_order-extension.git vendor/extensions/drag_order
rvm@localhost:path# rake radiant:extensions:drag_order:migrate

or install any other extension, it only outputs an error:

Have you already run rake db:bootstrap to get the database setup?

[Linutux]

Yes, I did that. And I already created a full website with Radiant, so the database is bootstraped for sure.

If it helps I could also send you my complete app_dir (including sqlite3 database).
