Rake won't run

[SamStuckey]

I'm very new to ruby and programing in general, forgive my ignorance. I'm trying to do a simple debugging exercise and am encountering an error that I can't make heads or tails of. When I try and run rake in the directory I get an error message about locating rspec?

(in /Users/Sam/Documents/learn_ruby-master)
rake aborted!
Gem::LoadError: Could not find 'rspec' (~> 2) - did find: [rspec-3.4.0]
Checked in 'GEM_PATH=/Users/Sam/.gem/ruby/2.2.0:/Users/Sam/.rbenv/versions/2.2.3/lib/ruby/gems/2.2.0', execute `gem env` for more information
/Users/Sam/Documents/learn_ruby-master/Rakefile:2:in `<top (required)>'
(See full trace by running task with --trace)

is there something I need to install or configure that I haven't?

Please file a bug report against learn_ruby because it doesn't say you need to install rspec 2 instead of the latest. In particular, [this instruction is wrong]((https://github.com/alexch/learn_ruby/blob/master/index.html#L51).

Run: gem install rspec -v '~> 2'to install the latest 2.x version of rspec (per this line of your error: Gem::LoadError: Could not find 'rspec' (~> 2) - did find: [rspec-3.4.0]).

Oh, this isn't a rake issue, so I will close it.
