Hello, I’m running into the following issue trying to run cucumber with the latest iron ruby source from git: c:/ruby/bin/cucumber:19: undefined method `bin\_path’ for Gem:Module (NoMethodError) This occurs when running either icucumber --help or the i18n cucumber sample. I’ve not tried any of the other examples. Yesterday morning I was able to get the scenarios in the i18n examples to partially execute until they failed with “Unable to cast from Func to BlockCallTargetN” and :0:in `concat’: can’t modify frozen object (TypeError)". exceptions, but after updating this morning I’m only seeing the undefined method exception. I’m currently sharing gems between MRI and Iron Ruby if that matters, and am using the instructions found here for cucumber: [http://wiki.github.com/aslakhellesoy/cucumber/ironruby-and-net](http://wiki.github.com/aslakhellesoy/cucumber/ironruby-and-net) Does anyone have any ideas? Or should I file a bug for this on CodePlex? Also if you need more information let me know. Thanks in advance, Matt ---

I added the following to [http://ironruby.net/Support](http://ironruby.net/Support). Could you send the exception information as described below? Bugs If you encounter a bug in IronRuby, or would like to ask for a feature, please submit an issue[http://ironruby.codeplex.com/WorkItem/Create.aspx](http://ironruby.codeplex.com/WorkItem/Create.aspx) to the IronRuby CodePlex project[http://ironruby.codeplex.com](http://ironruby.codeplex.com). A good bug report should include as much of the following information as possible: - IronRuby version - This is the output of “ir.exe -v” for binary releases, or the date and time when you did a GIT pull if you are building from sources, and if it is a Debug build or a Release build - Platform - Version of CLR, OS, machine type - MRI results - For pure Ruby code, does it work with ruby.exe - Exception information \* For cases where the exception backtrace is printed to the scree, full output of “ir.exe -ExceptionDetail” \* For cases where the application catches the exception, or if the backtrace is not accurate, the call stack from the Call Stack window in VS after running using “ir.exe -D”, and enabling catching of all Exceptions under the “Debug” menu.

I just copied the the bin\_path code from C:\path\to\ruby\lib\ruby\site\_ruby\1.8\rubygems.rb to \path\to\ironruby\libraries\lib\ruby\site\_ruby\1.8\rubygems.rb and it works fine with cucumber but I am now getting some new errors with a frozen object being called. I have also fixed the problem with expand\_path I removed Path and used a stack and parsed the path myself but I am a contributing noob and not sure really how to add this. But I was able to get rspec running with my .net code. I made a bat that calls spec (in ruby folder) mycode.rb using ironruby Matt Otto wrote: > Hello, > > I’m running into the following issue trying to run cucumber with the > latest iron ruby source from git: > c:/ruby/bin/cucumber:19: undefined method `bin\_path’ for Gem:Module > (NoMethodError) > > This occurs when running either icucumber --help or the i18n cucumber > sample.

Thanks for reporting these issues. I’m well aware of these issues with running Cucumber, and am working on getting it running today. The “frozen object” issue is with optparse, and Shri already has a fix for it. I’ll get the instructions updated on the cucumber wiki to run it with IronRuby. Merrell, if you have a fix to expand\_path, please commit/push it to your fork of IronRuby and send a link to the commit + some description to this list.
