"db:migrate rake aborted" error due to uninitialized constant Rake::FileUtilsExt_问答_开发者

I'm new to Ruby on Rails, and I've been trying to deploy a simple Cappuccino app with Ruby on Rails on to Heroku for the last three days, and every time I initialize (heroku rake db:migrate) I keep get the following error.

(in /app)
rake开发者_JS百科 aborted!

I've tried everything, and I am at my personal EOL. I've spent a good deal of time exploring the questions here and trying everything available.

I am receiving the same error on a new Heroku server with a new, tiny Rails application and have not received it before. Perhaps this is a new Heroku issue?

Pushing the local database with taps worked as a quick-fix, but is neither a scalable nor reasonable long-term solution:

$ sudo gem install taps
$ heroku db:push

There is a known problem with the version of Rake. Try rolling your Rake version back to 0.8.7.

See the Twitter remark from DHH (2011-05-21): Rake 0.9, which was released yesterday, broke Rails (and others). While we wait for a fix, you'll want to have gem 'rake', '0.8.7' in your Gem file.

How to fix the uninitialized constant Rake::DSL problem on Heroku? sounds similar.

Maybe try
