Question

while attempting to run rake, I run into the following error:

heroku rake db:migrate
rake aborted!

…and the trace:

Gemfile:

source ‘http://rubygems.org‘

gem ‘rails’, ‘3.0.7’
gem ‘rake’, ‘~> 0.8.7’
gem ‘sqlite3-ruby’, :require => ‘sqlite3’

I realize that other people have reported this error and asked the same question – the posted solutions have no effect on my issue, though. I’ve attempted every solution listed here: Undefined method 'task' using Rake 0.9.0.

Rails 3.0.8.rc1 has fixed this problem with rake 0.9.0, see this commit: https://github.com/rails/rails/commit/83f257fc4862642af29056cb5b7dfef6e1303754
