rake command gets "cannot load such file -- yaml/encoding" - ruby-on-rails

I want to use ruby-1.9.3-p194 on CentOS 5.8. I could install it with rvm and also system (libyaml and libyaml-devel were installed). But I can't run all of 'rake' tasks (not only 'rake spec').
I got "cannot load such file -- yaml/encoding". It's a sample result with trace. The 'rake' version is '0.9.2.2'. How can I resolve it?
$ rake spec --trace
rake aborted!
cannot load such file -- yaml/encoding

It's not a rake problem, it's a ruby <=> rails version incompatibility. You're using the most recent stable version of ruby with the rails version from the era of dinosaurs.
You need to do some hacking in order for them to understand each other!
Here's a nice read that should get you started:

Why am I getting this issue?
I am using Ruby 2.0.0 and Rails 4.1.5 on my OSX 10.11.16 Mac.
Well, the surface answer is because Ruby can't find google/api_client. ;) But obviously that's not super helpful.
First, try putting in place a couple of best practices:
Install RVM,
Create and use a gemset for your project (rvm use 2.0.0#my-awesome-project --create).
Run bundle install.
Then try the rake task again. What happens now?
(those best practices are RVM + gemsets)

rake db:schema:dump not working

Here is what shows up in console:

I just resolve a problem with the same error message.
In my case I was executing a migration with a class name previously defined in a model.
Maybe your MultiBox class is defined in some place.
I got 'superclass mismatch for class MultiBox' from prawn for every bundle exec I did after I apparently botched a huge git merge. It was very confusing, because I did not use MultiBox in my app. When I redid the merge, the error disappeared.
Use prawn-table instead of prawn-layout.

By your trace, it seems like it's a bundler issue,
running
gem update bundler
should fix it.

I tried uninstalling rake and re-installing it. Anyone else have the same problem?
Problem
You have an invalid statement in your Rakefile or Gemfile. You probably meant 'rspec' or 'rspec-rails' instead. Rake itself is telling you so:
cannot load such file -- spec
Solution
Remove the reference to "spec" in your Rakefile or Gemfile, or replace the problematic line with the correct name of the gem or library you're trying to use.
