Any idea how I can recompile the theme?

[Christian-Oette]

Try updating the dependencies in package.json (see https://www.npmjs.com)
e.g.

"devDependencies": {
"autoprefixer": "^6.5.4",
"grunt": "^1.0.1",
"grunt-contrib-clean": "^2.0.0",
"grunt-contrib-copy": "^1.0.0",
"grunt-contrib-cssmin": "^1.0.2",
"grunt-contrib-uglify": "^2.0.0",
"grunt-contrib-watch": "^1.1.0",
"grunt-postcss": "^0.8.0",
"grunt-sass": "^3.0.2",
"load-grunt-tasks": "^3.5.2"
...
"engines": {
"yarn": ">= 1.12.0"
},

and use yarn instead of npm and bower
