Error installing Homebridge on Raspberry Pi 3B

I have already got g+±6, Node.js 6.9.5, and mdns installes on my Raspberry Pi 3B. Yet I cannot install Homebridge using npm install -g homebridge or sudo npm install -g --unsafe-perm homebridge hap-nodejs node-gyp.

The error message is something like this:

make: Entering directory '/lib/node_modules/homebridge/node_modules/ed25519/build'
