Question

I don’t get why my script can’t find the gem that I just installed. Here is the code of main.rb

require 'exifr'

At this point I get

LoadError: no such file to load — exifr

error message

Here is the output of

gem environment

GEM PATHS:
     - /Users/me/.rvm/gems/ruby-1.9.3-p194

When I do

ls /Users/me/.rvm/gems/ruby-1.9.3-p194/gems/exifr-1.1.3/bin/exifr 

I get

/Users/me/.rvm/gems/ruby-1.9.3-p194/gems/exifr-1.1.3/bin/exifr

So the gem is in that location.
I’m running Mac OS Lion.
What I do wrong ?

//EDIT

gem list exifr

*** LOCAL GEMS ***

exifr (1.1.3)

1.9.3-p194 :001 > require 'exifr'
 => true 

Answer 1

when running ruby 1.9 you do not have to require rubygems anymore, so this should not be an issue.

looking at the bin directory is not of any use, cause the gems usually live in lib.

if you do a gem list exifr your installed gem should print out like

*** LOCAL GEMS ***

exifr (1.1.3)

the next step would be to try it out via the ruby REPL

$ irb
1.9.3p125 :001 > require "exifr"
 => true 
1.9.3p125 :002 > exit

this indicates that everything is installed fine.
