Ionic Build für iOS - ionische native/Core-Version Probleme

Question

Wenn Sie versuchen, die iOS-Plattform zu einem Ionic3-Projekt hinzuzufügen, bekomme ich einen seltsamen Fehler, dass eine neuere Version von ionic-native/Kern nicht erfüllt reqs alle sind ältere Versionen. Ich habe den neuesten Kern - wie kann ich das beheben, damit ich die Plattform hinzufügen kann?

ionic cordova build ios 
> cordova platform add ios --save 
Using cordova-fetch for cordova-ios@~4.3.1 

Error: Failed to fetch platform cordova-ios@~4.3.1 
Probably this is either a connection problem, or platform spec is incorrect. 
Check your connection and platform name/version/URL.

Answer 1

Dies ist auf ein ungeradees Problem mit npm (im Gegensatz zu global) nicht lokal installiert.

Um das Problem zu beheben, führen Sie npm install npm in dem Verzeichnis aus, in dem Sie die Plattform hinzufügen möchten. Dies wird auch die Pakete auf die korrekte Peer-Abhängigkeitsversion aktualisieren.

Dann erneut ionic cordova platform add ios ausführen.
