So, I don't really know what the error is, because it says that the program took too long to finish, and that I should check for infinite loops.

$VERBOSE = nil # We'll explain this at the end of the lesson.

require 'prime' # This is a module. We'll cover these soon!

def first_n_primes(n)

unless n.is_a? Integer

return "n must be an integer."

end

if n <= 0

return "n must be greater than 0."

end

prime_array ||= []

prime = Prime.new

for num in (1..n)

prime_array.push(prime.next)

end

return prime_array

end

first_n_primes(10)

So, the only thing I changed was the prime_array ||= [] and I don't see where the problem could be.

I tried again, and it worked.
