npx cap init fails: compilation terminated

Description of the problem: Following the getting started guide I did this:

mkdir capacitor cd capacitor npm install --save @capacitor/core @capacitor/cli npx cap init

The result:

../src/binding.cc:4:23: fatal error: pcap/pcap.h: No such file or directory
 #include <pcap/pcap.h>
                       ^
compilation terminated.

Phew!

Tried a ton of things, the one that finally got npx to “see it” was using this: npx @capacitor/cli init

Hope that helps others!

I have the same issue. npm -v: 6.9.0 node -v: v10.15.0

In my case, sudo apt-get install libpcap-dev seemed to fix that particular problem. That got me to command not found: cap instead, with a bunch of casting warnings.
