Installation Python and Gyp Error

I have python-3.7.2-amd64 and node-gyp installed (global), when I try to install the module with:
npm install node-bluetooth --save

I receive the following errors:

Beginne mit dem Paketinstallationsskript, das node-gyp configure build ausführt, und reproduziere npm install node-bluetooth mit den gemeldeten Windows-, Node.js-, node-gyp- und Python-Versionen. Vergleiche den Fehler bei der Überprüfung der gemeldeten Python-Version mit den unterstützten node-gyp-Anforderungen; abgeschlossen ist die Aufgabe, wenn die Installation des nativen Moduls erfolgreich abgeschlossen wird oder die Inkompatibilität mit einem verifizierten Workaround dokumentiert ist.
