Hi,
i have upgraded to doctest version 0.4.1.
Now when i try to run the example from the webpage, i get:
doctest: Interpreter exited with an error: ExitFailure 127
What's wrong here and how can i fix it?
Kind regards
Chris
This is the content of Fib.hs:
module Fib where
-- | Compute Fibonacci numbers
--
-- Examples:
--
-- >>> fib 10
-- 55
--
-- >>> fib 5
-- 5
fib 0 = 0
fib 1 = 1
fib n = fib (n - 1) + fib (n - 2)
main = do print $ fib 4
