[Sol1vaN]

Hi there,

I've a problem to launch your GUI interface:
I've installed all the pre requisites.

But, when I run the app, appers the following error:

freddy@raider-u64:~/Downloads/scapy-ui-master$ sudo ./scapy-ui.py --app
Traceback (most recent call last):
  File "/home/freddy/Downloads/scapy-ui-master/./scapy-ui.py", line 4, in <module>
    from flexx import flx, app
ModuleNotFoundError: No module named 'flexx'

Can you help me?
