Ruby 2.0.0 cannot load such file even though gem is installed

Question

I've tried all of the other solutions people have talked about on here, but none of them have helped / applied.

I've written a Ruby script that requires the spreadsheet gem. The requiring works fine when I execute the script normally with ruby myscript.rb , but after running chmod +x myscript.rb , and then trying to run the program with ./myscript.rb I get the following error....

/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:45:in `require': cannot load such file -- spreadsheet (LoadError)
from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:45:in `require'

from ./pmcnp.rb:7:in `<main>'

The beginning of my script looks like this:

#!/usr/bin/ruby

require 'rubygems'
require 'spreadsheet'

If anyone has any ideas, I would really appreciate it.

From your answers to the comments, the ruby you're running normally - and therefore the one in which your gems are installed - is /Users/fcangialosi/.rbenv/shims/ruby . When you make the script executable, it uses the hint in the script to know which program to use to execute the script. In your case, you have:

#!/usr/bin/ruby

So that's using whichever ruby version you have installed in /usr/bin/ruby . In order to use your rbenv ruby instead of /usr/bin/ruby , change the shebang line to:

#!/usr/bin/env ruby
