Installing Cucumber with Ironruby

Question

I'm trying to install Cucumber with ironruby. I followed instructions from http://wiki.github.com/aslakhellesoy/cucumber/ironruby-and-net . It downloads version 0.8.3 of cucumber and version 2.0.2 of gherkin. When i run cucumber i get the following error:

c:/ironruby/lib/ironruby/gems/1.8/gems/gherkin-2.0.2-universal-dotnet/lib/gherki

I've tried to set the MONO_PATH but that didn't seem to work. Any ideas?

Answer 1

I've been meaning to look into that. I think it has something to do with the new Ragel-based parser (Gherkin). It is compiled to a Java class, then compiled to a .NET assembly via IKVM. I think that in the process, it is taking a dependency on Mono.

Answer 2

I ran into this problem as well. The solution is to downgrade both cucumber and gherkin. Install gherkin 1.0.27 and cucumber 0.6.4 and it works. For reference: http://github.com/aslakhellesoy/gherkin/issues/issue/63

Well, you can get past that particular bug using this gist as the test runner:

Unfortunately, it then produces another error.
