I think two points about it:
Seems like you don't followed the
NativeScript quick setupto installed it because it could be installed all together. https://docs.nativescript.org/start/quick-setupYou should check inside your
package.jsonif this modules exists:
× Component tns-core-modules is not installed.
× Component tns-android is not installed.
× Component tns-ios is not installed.
You also check doing this: npm ls <module-name>, where <module-name> is the module to check it.
Let me know if it help you.
