Problems about requiring gems

Ruby

Hello. I tried to run examples in Rubymacros, but I could not make it
work. Could I get any help?

RDoc failure in lib/macro.rb at or around line 57 column 24

Before reporting this, could you check that the file
you’re documenting compiles cleanly–RDoc is not a
full Ruby parser, and gets confused easily if fed
invalid programs.

The internal error was:

ERROR: While executing gem … (NoMethodError)
undefined method `name’ for nil:NilClass
