Can't build - node-gyp problem?

[rbarkas]

When I try to install pm2-web I get the following error. Am I doing something wrong?

sudo npm install -g pm2-web

pm2-web has installed on your system but it's failed to compile mdns2 along the way.

If failed because you don't have dns_sd.h on your system. Depending on your distro you may be able to get it by running something like:

apt-get install libavahi-compat-libdnssd-dev

In practical terms mdns2 lets pm2-web advertise itself to the local network via Bonjour (Avahi on Linux). The dependency is optional so if you don't care about this functionality the error is safe to ignore.

Thanks, that did the trick
