I've been following this guide and I keep getting the error "unknown authentication strategy 'google'". I've no idea what's going on and I already tried searching the other answers with little success. Any help would be appreciated, thanks!

It looks to me you are not calling require('./passport.js')(passport) (or whatever the path is) at all ie. you are not configuring passport. My assumption is maybe further backed up by the fact that if you would include that code from passport.js you would see SyntaxError: Unexpected token ; because, removing parameters and excess stuff, this is what you define:
passport.use(new GoogleStrategy({}, passport.serializeUser(function(user, done){});
passport.deserializeUser(function(id, done) { });
function(token, refreshToken, profile, done) { });
If you're gonna follow that tutorial you should have taken a look at the first part that defines the base application. In your admin.js, add require('./passport.js')(passport) after the line require('passport')
