NoMethodException

I am running IronRuby 1.1.3 as installed from NuGet. It is loading a
very simple script that creates a class and calls a method on that
class. This exception is thrown:


System.MissingMethodException: Method not found:
‘Microsoft.Scripting.Actions.Ca
lls.OverloadInfo[]
Microsoft.Scripting.Actions.Calls.ReflectionOverloadInfo.Crea
teArray(System.Reflection.MemberInfo[])’.

Builder, CallArguments args, String methodName)

The ruby code being loaded:

class MyClass

def run
puts 'Hello, World!'

end

end

hello = MyClass.new


I have all of the required references set IronRuby, IronRuby.Libraries,
IronRuby.Libraries.Yaml, Microsoft.Scripting,
Microsoft.Scripting.Metadata, Microsoft.Dynamic.

I downloaded the binaries and referenced those files directly and still
same issue.

I installed the IronRuby package as well and from the command promp I
get the same error. Any idea what’s going on here?

There was another thread with this same issue but the system told me to
start a new topic as that one was old.

Can you give an example of the ruby code that is failing?

The error indicates IronRuby is having trouble finding an appropriate
constructor to call for a C# class
Can you give some more information about the class you’re trying to
instantiate? eg

  • What constructors does it have
  • Are they private/protected
  • What parameters does each have
  • anything else that might be relevant
