gems madness - require path hoopty?

[Giles Bowkett]

There's a nifty gem called MP4Info which enables you to get ID3-style
metadata from non-MP3 files, such as AAC files. It's dag gol darn
usefulness and then some, but my attempts at requiring it were
troubled.

This works:

sudo gem install MP4Info

This works:

require '/opt/local/lib/ruby/gems/1.8/gems/MP4Info-0.3.1/lib/mp4info'

These don't:

sudo gem install mp4info
require 'mp4info'
require 'MP4Info'
require 'MP4Info-0.3.1'
require 'MP4Info-0.3.1/lib/mp4info'

Besides a test script and a few bits of test data, .wav files etc.,
mp4info.rb is basically the only file in the gem. Is there anything
obvious I'm missing here?

gemspec.rb

Did you also maybe forget to add

require 'rubygems'

to the top?

Yep, that's missing all right. I bet the gem would work better if it
had a gemspec file. I'm just guessing here, but I think you're right.

$ gem install MP4Info -i ~/tmp/gems
[...]
$ GEM_HOME=~/tmp/gems gem which mp4info
/Users/drbrain/tmp/gems/gems/MP4Info-0.3.1/lib/mp4info.rb
$ GEM_HOME=~/tmp/gems ruby -rubygems -e 'require "mp4info"'
$

There's nothing wrong with the gem.

a) You didn't require 'rubygems' before require 'mp4info'
b) `gem env`'s ruby doesn't match `which ruby`'s ruby.
