Ubuntu – Error "ModuleNotFoundError: No module named 'pylibpcap'"

I’m trying to use this Python libpcap library:

https://pypi.org/project/python-libpcap/

I have installed using:

sudo apt-get install libpcap-dev
pip3 install python-libpcap

but when I run the capture example code in script using sudo python3:

from pylibpcap.pcap import sniff

for plen, t, buf in sniff("my_interface", count=-1, promisc=1, out_file="pcap.pcap"):
    print("[+]: Payload len=", plen)
    print("[+]: Time", t)
    print("[+]: Payload", buf)

I get this error:

   from pylibpcap.pcap import sniff
ModuleNotFoundError: No module named 'pylibpcap'

How can I fix this/what’s wrong?

I’m on Ubuntu 22.04.
