Ruby loadError when running require 'gemname' on irb

Question

I am making a gem and I want to test it on irb.

I ran gem build gemname.gemspec, then gem install ./gemname-0.0.0.gem successfully. The gem name appeared on gem list under local gems.

When I am in irb and require 'gemname', it shows

LoadError: cannot load such file -- gemname
    from /Users/iggy/.rvm/rubies/ruby-2.2.1/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in `require'
    from /Users/iggy/.rvm/rubies/ruby-2.2.1/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in `require'
    from (irb):1
    from /Users/iggy/.rvm/rubies/ruby-2.2.1/bin/irb:11:in `<main>'

I have looked at answers by this post, this one, this one,and a few more. Still getting LoadError.

My gem environment:

More info:

Igors-MacBook-Air:gemname iggy$ which ruby
/Users/iggy/.rvm/rubies/ruby-2.2.1/bin/ruby

Made sure there is only one ruby running (there was two versions, but I changed it to what is shown below)

Igors-MacBook-Air:gemname iggy$ which -a ruby
/Users/iggy/.rvm/rubies/ruby-2.2.1/bin/ruby

Current ruby ver

Igors-MacBook-gemname iggy$ ruby -v
ruby 2.2.1p85 (2015-02-26 revision 49769) [x86_64-darwin14]

Not sure what this command does, but one of the posts I saw prior recommended to run this:

Igors-MacBook-Air:gemname iggy$ gem env | grep 'RUBY EXECUTABLE'
  - RUBY EXECUTABLE: /Users/iggy/.rvm/rubies/ruby-2.2.1/bin/ruby

Any help to get rid of require 'gemname''s loadError would be highly appreciated.

Try `require 'rubygems'` and then require the gem that gave you the error. — 13aal, Jul 01 '16 at 21:10
As a note, putting a capital `N` in your gem name is going to drive people nuts. The convention is lower-case only. The packages that do flout this rule stand out as irregular. Do you have a `gemName.rb` file? — tadman, Jul 01 '16 at 21:14
@13aal I did that and it returns false. It seems like it was already loaded.When I require 'gemname' it returns the error. I will change the camelcase. I do have the gemname.rb inside folder named lib. The gem follow convention from http://guides.rubygems.org/make-your-own-gem/ (not exactly the same)- it has at least gemname.gemspec, lib folder, and gemname.rb — Iggy, Jul 01 '16 at 21:35

Problem solved.

First I create, on gemname folder, Gemfile. Inside looks like:

# A sample Gemfile
source "https://rubygems.org"
gemspec
# gem "rails"

Reinstalled the gem, Gemfile.lock was created.

Then I ran irb via bundle exec irb instead of typing irb.

require 'gemname' works.
