I’m having a great deal of trouble getting rake to run migrations on our staging server. Everything works fine on my dev box, but trying to run the following on staging results in errors. * * * > rake db:migrate > (in /var/www/apps/acadtech2/app) > rake aborted! > Don’t know how to build task ‘db:migrate’ ## (See full trace by running task with --trace) The box has Ruby 1.8.4 and Rails 1.1.2. Any hints or suggestions appreciated. Thanks, Chris ---

Hello Chris, > ## (See full trace by running task with --trace) > > The box has Ruby 1.8.4 and Rails 1.1.2. > > Any hints or suggestions appreciated. I haven’t the solution (are you sure you runned the command in RAILS\_ROOT ?) but first, be sure you’ve got the right list of tasks by checking with : $ rake --tasks – Jean-François. ---

Hi Jean-François, I know for sure that I’m in the RAILS\_ROOT directory, but when I run the $ rake --tasks command, I get an empty list. Any idea what could cause this? Thanks, Chris ---

Solved the problem - somehow my Rakefile had gotten cleaned out. I replaced it with one from another app and it is working fine now. Thanks for the help. -Chris ---

No idea, but I would check all I can check. - Rake, - Gems Rails. Are they many versions of Rails installed ? - Rails code in vendor/rails if the application is frozen, - create a dumb Rails app, and run inside rake --tasks that’s the first suggestions I’ve got in mind. HTH, – Jean-François.
