Error running the helloworld app


Please, what is the meaning of the boring error “Unable to apply changes on device: emulator-5554. Error is: Command npm.cmd install tns-android@3.4.1 --silent --save-exact --save failed with exit code 1.”


Hey @cizu64,

Sorry you ran into problems here, and this is a weird one. Could you let us know…

  • Are you on Windows, macOS, or Linux?
  • What version of Node and npm are you using?
  • What command were you trying to run when you got that error?
