VueGL is not defined

You do NOT need this line;

Object.keys(VueGL).forEach(name => Vue.component(name, VueGL[name]));

This line tries to register all of VueGL properties as components, but the VueGL object is not defined because you don't load whole exports of 'vue-gl' module.
And Vue.component() method is for global component registration. Commonly it is preferred to use local registration in single file components as it limits the component name context.

You already register the VglRenderer locally in your component, so it should work just after removing the line above.
Remember that you need to add the VglScene and other components to components property when you call these components in template.
