node-gyp rebuild error while installing an npm package - node.js

Question

I'm trying to install "karma" and "grunt-karma" for a project and I end up with the following npm error. I'm running MacOS Sierra v10.12.4, XCode v8.3.2 with command line tools installed, node v7.9.0, node-gyp v3.5.0.
Before pasting this here I read all the SO topics about this and also some other ones on GitHub, but nothing worked.
