ruby splat operator compilation error in eclipse but runs fine on command line

Question

I have the following ruby script ruby_test.rb in eclipse (DLTK/RUBY), which throws a compilation error and I am not able to run in eclipse. This makes sense since *arr should be the last parameter. But when I run it on command line ( ruby ruby_test.rb ) its runs fine. any idea why?

My installed ruby version is 2.1.6p336

#!/usr/bin/ruby

arr = [1,2,3]

def test(a1,a2,a3,a4,a5)
   puts "The first number  is #{a1}"
   puts "The second number is #{a2}"
end

test(0, *arr, 4)

Answer 1

也许您在Eclipse上有一个旧版本的Ruby，在该版本上，最后一个参数必须是splat参数。
