[Haskell-cafe] Convert IO Int to Int

I have tried on the console to write
x <- randomRIO(1,10)
Everythings fine and the type of x is
x :: Integer
Now I have tried to write a Method which gives me a Number of random numbers
the same way but it doesn't work.
randomList :: Int -> [Integer]
randomList 0 = 
randomList n = do
r <- randomRIO (1, 10)
It says Couldn't match expected type `IO t' against inferred type `[t]'
r <- randomRIO (1,10) causes an error. But why does it work on the console?
Is there a way to solve it another way?
