TypeError: super() takes at least 1 argument (0 given)

Hello
I run below code but got TypeError
`import serial
from pexpect_serial import SerialSpawn

with serial.Serial('/dev/ttyUSB0', 115200, timeout=0) as ser:
ss = SerialSpawn(ser)
ss.sendline('start')
ss.expect('done')`

console show
Traceback (most recent call last):
File "serial_test2.py", line 5, in
ss = SerialSpawn(ser)
File "/usr/local/lib/python2.7/dist-packages/pexpect_serial/serial_spawn.py", line 41, in init
super().init(None, **kwargs)
TypeError: super() takes at least 1 argument (0 given)

OS Ubuntu 16.04 64bit
Python 2.7.12

Any idea?

That form of super() is a Python3 only usage. My guess is that pexpect-serial is not python2 compatible.
