rspec error when running rake - ruby

I'm a noob, working through a tutorial which many here may know (testfirst.org). I'm getting the error below in terminal.app, when I try running 'rake':
fname-lnames-macbook-pro:00_hello macbookowner$ rake

My questions: What is going wrong? And how can I fix it?
Info:
I got the same/similar error running rvm 1.9.3 and rvm 2.0.0
I installed 'gem install rspec' on both rvm versions
My best guess is that the hello.rb file [which I created in Sublime Text 2, and saved on macbookowner ->Desktop] is not being found by rake. When I run ls on Desktop, it does show hello.rb.
Thanks in advance!

If you look at the error,
/Users/macbookowner/Desktop/learn_ruby-master/00_hello/hello_spec.rb:116:in 'require': cannot load such file -- hello (LoadError)
it shows that in hello_spec.rb, on line 116, there is a require 'hello' statement which is failing. Likely the file does not exist at the path specified.

Bundler doesn't permit using gems in project home directory

I'm working on a program that assists in running Ruby code on the command line (at https://github.com/keithrbennett/rexe, gem install rexe).
When I gem install it, and cd to the project root, and try to require a file not in the Gemfile, it fails:
➜ rexe git:(master) ✗  rexe -r awesome_print -oa '"hello"'
Traceback (most recent call last):

/Users/kbennett/work/rexe/exe/rexe:385:in `require': cannot load such file -- awesome_print (LoadError)
However, when I cd ~, it works fine:
➜ ~  rexe -r awesome_print -oa '"hello"'
"hello"%
I wrapped my code in Bundler.with_clean_env, which I thought should take care of this.
I can use the Ruby interpreter directly and it works:
➜ rexe git:(master) ✗  ruby -r awesome_print -e "ap 'hello'"
"hello"
So I guess Bundler is making an assumption that non-Gemfile-listed gems should not be permitted to be loaded, and that is almost always reasonable, but in my case, where the program should be able to load any gem whatsoever, it is an impediment.
I understand that Bundler is finding the Gemfile[.lock] and doing what it thinks is right, but is there any way around this?
Not a complete answer, just a direction: try adding the path to the requested gem to $LOAD_PATH explicitly before requiring the gem. For example:
pry(main)> require "awesome_print"
LoadError: cannot load such file -- awesome_print
But then
pry(main)> $LOAD_PATH << "<home>/.rbenv/versions/2.5.3/lib/ruby/gems/2.5.0/gems/awesome_print-1.8.0/lib/";
pry(main)> require "awesome_print"
=> true
Voila! The question is how to get the proper path for the gem, maybe gem which could help...

gem install of pdf-extract on Macports / Mac OS X Yosemite

I am attempting to install pdf-extract on Mac OS X Yosemite. I assume it's better not to use the /usr/bin/ruby that comes with Yosemite, so I'm using the Macports version, /opt/local/bin/ruby (ver2.1.3).
The installation appears to go fine:
sudo port install ruby
sudo port install rb-rubygems
sudo port select --set ruby ruby21
which ruby #/opt/local/bin/ruby
which gem #/opt/local/bin/gem
sudo gem install pdf-extract
At the end of the last command, the message appears to indicate that all went well:
...

15 gems installed
However, when I attempt to run pdf-extract, I ran into the following error:
$ cd bin/
$ ./pdf-extract extract --titles journal.pdf
/opt/local/lib/ruby2.1/gems/2.1.0/gems/commander-4.2.1/lib/commander/runner.rb:384:in `block in require_program': program version required (Commander::Runner::CommandError)

from ./pdf-extract:5:in `<main>'
My question is whether I've done the gem install correctly (and therefore it's probably a bug in pdf-extract) or whether I've messed up something in the installation (or in the file paths).
Side note: the installation folder was initially $HOME/Dropbox/code/ruby/pdf-extract, but I carried out a mv pdf-extract /tmp (to shorten the file paths in the error messages) and re-ran the install scripts (the error message essentially remained the same). I also tried replacing ./pdf-extract with /opt/local/bin/ruby2.1 pdf-extract but it did not help.

Unable to run serverspec due to gem being unable to load

I'm trying to play around with serverspec, however it seems I have some weird gem error that I cannot pinpoint.

Still, when I look at the list of gems, serverspec is there (1.9.0). I've also checked it's existance in gems directory. I'm running a system version of ruby 1.8.7 and I do not have multiple ruby installations.
I'm not really sure where to go from here. Thanks in advance for any help.
What helped was:
1) Upgrading ruby package on the system (still 1.8.7).
2) Upgrading rubygems.
3) Removing all gems.
4) Installing serverspec and rake again.

Why do I get "RAKEFILE ABORTED, NO RAKEFILE FOUND"?

I am attempting to take an interactive Ruby test to no avail.
I downloaded the zip file with no problems and followed the directions for
the terminal command line where I continue to get the following error. I
am using "Ruby 1.9.3p392 (2013-02-22 revision 39386) [x86_64-darwin10.8.0]".
If anyone can offer any help or suggestions thank you in advance.
INSTRUCTIONS:
Install RSpec
gem install rspec
Enter the course directory. (That's the same directory that this
index.html file is in.)
cd learn_ruby
Enter the 00_hello lab.
cd 00_hello
Open a terminal in this directory
cd 00_hello
This directory is the starting point for this exercise. It contains a
spec file and you'll be adding a ruby file to (eventually) make the
specs pass.
Run the test
rake
Watch it fail
You should see an error. Don't get scared! Try to read it and figure out
what the computer wants to tell you. Somewhere on the first line it
should say something like
no such file to load -- test-first-teaching/hello/hello (LoadError)
I do not get this error message, I get the one below:

Error when trying to run RSPEC. Why?

I can't figure out why my RSPEC isn't working. I reinstalled RSPEC with sudo gem install rspec and then tried again to install with a specific version number (sudo gem install rspec -v 2.11.0)
I continue to get the following error message and I cannot figure out what it means. I believe that I may or may not have version 1 also installed, not sure.
