Permutations with replacement python

I am trying to produce all possible permutations of 1 and -1 of length n. If I use itertools.permutations , it will not accept a repeat length greater than 2, because of not allowing repetitions. If I use itertools.combinations_with_replacement , then not all of the permutations are produced.
