I am trying to install the netifaces module and was able to run the tar xvzf netifaces-0.11.0.tar.gz command. It looks like it extracted all the folders it needed too but I dont see them in my download folder or in my site-packages under my python folder which is where I saw everything should go to be imported in python.
I ask because to run the install it says on their page to cd to the folder it extracted and then run the setup.py file.
you can see what is inside tar.gz. here is a guide https://www.cyberciti.biz/faq/list-the-contents-of-a-tar-or-targz-file/
also, didn't you forget about "-" ?
tar -xvzf netifaces-0.11.0.tar.gz
