I have IronRuby 1.0 with RubyGems 1.3.6 and Bundler 0.9.25.

When I run Bundler.setup I get this error:

NameError: undefined method `gem' for module`Bundler::SharedHelpers’  
from  
C:/IronRuby-1.0/lib/ironruby/gems/1.8/gems/bundler-0.9.25/lib/bundler/shared\_helpers.rb:90:in

from C:/IronRuby-1.0/lib/ruby/1.8/irb.rb:69:in `start’  
from C:/IronRuby-1.0/bin/irb:13

reverse\_rubygems\_kernel\_mixin looks like this:  
def reverse\_rubygems\_kernel\_mixin  
# Disable rubygems’ gem activation system  
::Kernel.class\_eval do  
if private\_method\_defined?(:gem\_original\_require)  
alias rubygems\_require require  
alias require gem\_original\_require  
end

```
    undef gem
  end
end

```

If I run this in irb I get this error:  
NameError: undefined method `gem' for class`Object’

```
  ::Kernel.class_eval do
    undef gem
  end

```

Any ideas?

## try doing a require ‘rubygems’ as first line in your file. That should make the gem method available

Looks like IronRuby bug. This works in MRI but doesn’t in IronRuby:

module Kernel  
def gem  
end  
end

module M  
Kernel.class\_eval do  
p method(:gem)  
undef gem  
end  
end

Will look at it. Thanks for reporting the issue.

Should be fixed now in our internal repo. You can apply the attached  
patch if you want to try it before we push the sources out.

Tomas where do I find your internal repo?  
I had a look on github but there do not seem to be any recent commits.

I already am:

require ‘rubygems’  
require ‘bundler’  
Bundler.setup

I have also applied this fix (if it makes a difference)  
[http://marcinobel.com/index.php/bug-invalid-exec\_format-ir/](http://marcinobel.com/index.php/bug-invalid-exec_format-ir/)

Other than that it is a fresh IronRuby 1.0 install
