Hey guys,

I’ve been having a difficult time getting my IronRuny 1.1.1 working  
properly. ir.exe now seems to be working, but igem is giving me a  
“unknown:  
no such file to load – gem\_prelude.rb (LoadError)” when I run it.

I’m not sure where to go from here. Just in case, I have RUBYOPT set to  
rubygems and even tried doing a “require ‘rubygems’” in my  
lib\ruby\1.9.1\gem\_prelude.rb, to no avail.

Any ideas?

Mike

Hi Mike,  
The issue has been found and file in at  
[http://ironruby.codeplex.com/workitem/5326](http://ironruby.codeplex.com/workitem/5326) . I’m investigating it.

I found same error as you do “no such file to load – gem\_prelode.rb”  
this should appear when you try to call igem.bat . It didn’t happen  
when i use “ir.exe c:\githup\ironruby\Scripts\bin\gem install rspec”

I should able to fully look at this issue over weekend.

Best,
