Has anyone successfully installed the pcapy python module on SNG7? I keep getting gcc errors no matter which version of python or pip that I install. I have followed the below links to no avail.

I can install other modules. Below is the error when installing pcapy:
[root@freepbx ~]# pip3 install pcapy

I was struggling with pip3 for gTTS and the below worked for me but I see you have that cited already
Yeah other modules like dpkt install fine with pip3 just not pcapy. I am close to figuring it out and if I do I’ll post back here, just wondering if anyone had specific experience with that module.
So I have to use python 2.7 in order to get it to work. The reason I can’t get it to work with python 3 is I am missing dependency python3-devel but it won’t let me install it due to file conflicts with python3.6u. So:
yum install python-devel
yum install libpcap-devel
curl https://bootstrap.pypa.io/pip/2.7/get-pip.py --output get-pip.py
python get-pip.py
pip install pcapy
It warns about 2.7 being EOL but it seems the only way to get it to work on SNG7. I cannot remove or modify 3.6u because sangoma-pbx.noarch is a dependency.
