Firebase-tools: Firebase Deploy-Befehl fehlgeschlagen (Fehler Muss entweder "site" oder "target" in jeder "hosting"-Konfiguration angeben.)

Ich habe versucht, den Befehl "firebase deploy" auszuführen, um eine App in Firebase bereitzustellen, aber ich hatte den Fehler, den ich in Klammern im Titel erwähnt habe:

 Error: Must supply either "site" or "target" in each "hosting" config.

So sieht meine .firebaserc-Datei derzeit aus:
```.firebaserc
{
"Projekte": {
"default": "phonestore-4e40c"
},
"Ziele": {
"phonestore-4e40c": {
"hosting": {
"Telefonladen": [
"phonestore-4e40c"
]
}
}
}
}

What do I do here to fix the error?  I tried adding `"target":` before `"phonestore-4e40c"` (it would become `"target": "phonestore-4e40c"`) but that didn't work either; it gave me this error:

! JSON-Fehler beim Laden von E:\programming\angular\phone-store.firebaserc

=== Bereitstellung in 'phonestore-4e40c'...

Ich stelle Hosting bereit

Fehler: Muss in jeder "Hosting"-Konfiguration entweder "site" oder "target" angeben.

(This is almost the same as the one I got when I ran just `firebase deploy`; the only thing new is the line about a JSON error).  

Any help with this is much appreciated.  (Note: The reason I didn't open a "Bug Report" issue is that I wasn't sure if my issue qualifies as a bug report.)

Before that I had tried the `ng deploy` command since I was following the Angular Getting Started Tutorial and had gotten to the deployment part after following the whole thing ([here](https://angular.io/start/start-deployment)).  I'd chosen to deploy it to Firebase after downloading it to my computer.  The result of that was this:

ng bereitstellen
Aufbau eines "Telefonladens"
Generieren von ES5-Bundles für differentielles Laden...

`` Would be good if I could get this to work. If not, then the firebase deploy` Befehl würde auch gut funktionieren.
