Can't load gem grit.

[hungerandthirst@…]

Sorry to be so specific about not being able to load a specific gem. I do this:

require 'rubygems'
require 'grit'
include Grit

and get

in `require:': undefined method `[]' for nil:NilClass (NoMethodError).

It seems to be coming from the

require 'rubygems'

inside of grit.rb. If I disable this line, it includes it with the following warnings:

unknown: warning: already initialized constant VERSION
unknown: warning: already initialized constant MEDIA_TYPE_RE
unknown: warning: already initialized constant UNREG_RE

I recently upgraded to MacRuby 0.6 hoping it would fix this issue.

When I attempt to load the grit gem in macirb:

$ require "rubygems"
$ require "grit"

Results in:

"no such file to load -- grit"

but if I

$ require "grit"

again, I get:

unknown: warning: already initialized constant VERSION
unknown: warning: already initialized constant MEDIA_TYPE_RE
unknown: warning: already initialized constant UNREG_RE
unknown: warning: already initialized constant ENCODING_RE
unknown: warning: already initialized constant PLATFORM_RE
unknown: warning: already initialized constant SIGNATURES
unknown: warning: already initialized constant IANA_URL
unknown: warning: already initialized constant RFC_URL
unknown: warning: already initialized constant DRAFT_URL
unknown: warning: already initialized constant LTSW_URL

unknown: warning: already initialized constant VERSION

SyntaxError: compile error
	from /Developer/Examples/Ruby/MacRuby/(irb):3:in `<main>'

And if I try to require grit in a MacRuby project I get the same:

undefined method `[]' for nil:NilClass (NoMethodError)

Any tips on how I might go about debugging this? It's driving me crazy.

Basically the work around I found for this on MacRuby 0.6 on SL:

require "rubygems"
require "grit" rescue p "Errors occurred while trying to load Grit"
require "grit" rescue p "Errors occurred the 2nd time too!!!"

The second require shows "unknown: warning: already initialized constant *" warnings, but the Grit gem is loaded, and should be available after the second require statement.

Could you try with trunk? Here's what I get:

$> macruby -r rubygems -r grit -e 'include Grit'
$>

Seems to work without warnings ;-)

There has been so response for 6 months and is still seems to work fine so closing.
