Problems with let otree devserver run

I have a Python Code to conduct an experiment. To ensure that the Code is working smoothly I wanted to run a trial round via 'otree devserver', but I always get an AttributeError message and I am stuck here. Can anyone help me out?
I have downloaded the Code from GitHub and downloaded all required packages. I am using macOS, otree-5.10.2 and django-4.1.7. Here is my full traceback / error message:

Any hints on how can I get rid of it ? I will update this post with any necesarry information that you'll need.

Update the python version to 2.7 or greater. One of the problems is that you don't have argparse which is on the newest version of python.

OSError: Result too large

I'am playing around with scapy but i cant get it to work. I tried different code's but all gave me the same output:
Traceback (most recent call last):
File "<module1>", line 7, in <module>
File "C:\Python26\lib\site-packages\scapy\sendrecv.py", line 357, in srp
s = conf.L2socket(iface=iface, filter=filter, nofilter=nofilter, type=type)

self.outs = dnet.eth(iface)
File "dnet.pyx", line 112, in dnet.eth.__init__
OSError: Result too large
Iam using python 2.6 with all dependencies installed for scapy.
How to fix this?
