heroku rake migrate not working

Question

I am just trying to simply do the following:

my@ubuntu-lappy:~/rails/app_soft$ heroku rake db:migrate
rake aborted!
Please install the  adapter: `gem install activerecord--adapter` (no such file to load -- active_record/connection_adapters/_adapter)

What am i doing wrong?

In the past I've successfully ran heroku rake db:migrate

gem list shows

activerecord (2.3.5, 2.2.2)

I have a similar problem, and I suspect that is may be a problem with the instance you're currently on. When I try to run "heroku info", it gives me an internal server error. It may have something to do with the heroku's database.yml referencing a bad value. I'm still waiting to hear back from them.

This can happen if the app gets instantiated incorrectly. As a workaround you can rename the app to get it out of the way and create a new one. You'll likely need to open a support request to get the wedged app deleted.
