I'm trying to teach myself some ruby using the app academy tutorials and after doing the readings, installing rvm,rubygems and rspec2 when I even try to run the first most basic code (00_hello) with rake I get the whole error :

I tried to google some of the errors, but with no success. I had previously another error with the rake file using rspec v2 and the current version is 3.0.0, so I had to install the older and I think it might be another setup problem. Thanks if someone can help me or direct me.
rspec_config.rb file :
RSpec.configure do |c|
c.fail_fast = true
c.color = true
end
hello.rb file:
def hello
"Hello!"
end
def greet(who)
"Hello, #{who}!"
end
UPDATE
Getting new error as :-
While I changed c.color = true to c.color_enabled = true
(in /home/deadpool/Documents/learn_ruby)

UPDATE
hello_spec.rb file :
require "hello"
describe "the hello function" do
it "says hello" do
hello.should == "Hello!"
end
end
describe "the greet function" do
it "says hello to someone" do
greet("Alice").should == "Hello, Alice!"
end
it "says hello to someone else" do
greet("Bob").should == "Hello, Bob!"
end
end
UPDATE
So, I updated rspec to v3.0.0 and changed Rakefile gem 'rspec', '~>3.0.0' and c.color = true back. Everything is working now(getting some deprecation warnings, but nothing critical), getting the output that is in the tutorial. Guess I just had to updae my rspec and change the version in the Rakefile. Thank you so much :)
Your error log is showing you are in rspec-core-2.0.0 version and your error is saying -
rspec_config.rb:3:in `block in <top (required)>': undefined method `color=' for
#<RSpec::Core::Configuration:0x0000000293dee0> (NoMethodError)
Now Deprecate config options confirms that below versions of 2.99.0.rc1 / 2014-05-18 or 2.99.0 methods were - #color_enabled, #color_enabled= and #color?. Which are changed since 2.99.0 to #color, #color= and #color_enabled?.
I got the information from the changelog as I linked -
Deprecate #color_enabled, #color_enabled= and #color? in favour of #color, #color= and #color_enabled? output. (Jon Rowe)
Thus you need to write as
RSpec.configure do |c|
c.fail_fast = true
c.color_enabled = true
end
Regarding your new error, I found it as a bug undefined methodrun_all' for []:Array`. Which has been fixed in this patch. Check this Rspec issue.
My suggestion use Rspec 3.0, at least you will be happy. In this case revert the color_enabled to color.
Hope this would help you.

i'm developing a simple net application (packed as a gem) to learn Ruby and TDD.
I have this class (receiver.rb):
require 'eventmachine'
class Receiver < EM::Connection
def initialize(port)
EM.run do
EM.open_datagram_socket('0.0.0.0', port, self)
end
end
end
And this test (receiver_spec.rb):
require "spec_helper"
require "net/receiver"
describe "Receiver" do
it "can istantiate" do
#rec = Receiver.new(500)
end
end
Anyway, when i run rspec it prints out this:
1) Receiver can istantiate
Failure/Error: #rec = Receiver.new(500)
TypeError:

I'm quite new to the ruby environment, so if i missed something let me know.
I'm not sure what documentation you're working from, but it appears the open_datagram_socket requires a Module and cannot accept a Class as the third (handler) argument.
Per the comment in http://www.rubydoc.info/github/eventmachine/eventmachine/EventMachine.open_datagram_socket, it appears this restriction may have been loosened in a later version of EventMachine
I had a test case of the following form:
require 'test/unit'
class SomeTests < Test::Unit::TestCase
def test_should_do_action
assert true
end
end
and have re-written it using must as suggested in the book A Test::Unit Trick to Know About:
require 'test/unit'
class SomeTests < Test::Unit::TestCase
must "do action" do
assert true
end
end
And when I run it, I get an undefined method 'must' error shown as follows:

I thought that must might be a part of minitest, so I required 'minitest/unit' instead, but I still get an error. I also assume that must keyword isn't part of rspec, which I'm not using yet.
How do I get this to work properly?
It looks like that method is not provided out of the box, but was developed by a third party. You need to add code described here.
I am working through some Ruby problem sets. I'm using Ubuntu 14.04, rbenv 0.4.0-98-g13a474c, rspec 3.1.4, and ruby 2.0.0p353. I'm running into the following errors for every test I run and I'm hoping someone might be able to guide me in the right direction to a solution.
I have run rspec tests successfully in the past but I can't seem to figure out the issue with my current setup.
Here is the message I receive for every test I run:
6) age is an integer

Edit: Here is an example of one of the spec files, however, the issue comes up on about 20 spec files. I know my solutions are correct and my peers aren't having the same issues I am:
first_name = "M"
last_name = "R"
age = 23
describe 'first_name' do
it "is defined as a local variable" do
expect(defined?(first_name)).to eq 'local-variable'

end
end

end
end

The error is happening inside ActiveSupport::BufferedLogger#add method call and you appear to be monkey-patching this class. The internals of ActiveSupport::BufferedLogger have likely changing between the versions of Rails you're using.
Try removing all of the ActiveSupport::BufferedLogger code from your environment.rb to work past this error and get your app running. Then, if you still need the monkeypatch (don't know why), you'd have to rewrite it on top of the newer version of the class.
I'm trying to stub out a Class method for any instance of the class (via any_instance). My tests run through successfully, but at the end of the test when rspec is trying to reset the any_instance stub, it throws an error (Unable to find matching line from backtrace). Here's the apparent culprit line of code (removing it removes the error):
Confetti::Config.any_instance.stub(:write_info)
The full error is below. Seems like stub should've (but fails to) created the __rspec_original_dup method, and when the reset happens, it can't find the expected method.

I solved this by simply using Rspec v2.10.0 instead of v2.11.0:
gem 'rspec', '~> 2.10.0'
From the links that Henrik provided, it sounds like they may release a bugfix for Rspec. Watch this issue for more information. In the meantime, downgrading solved the issue for me.
(Thanks for your work in helping me figure this out, Henrik.)
