TypeError: 'NoneType' object cannot be interpreted as an integer

it's easy to fix, just modify pwnlib.term.readline.raw_input:

def raw_input(prompt='', float=True):
    ...
    return readline(None, prompt, float)

to

def raw_input(prompt='', float=True):
    ...
    return readline(-1, prompt, float)
