npm run dev

Ionic CLI Commands

When developing a web app, progressive app or native mobile app, all of the Ionic CLI commands are available when you are in the src directory, as this is a standard Ionic app. Change into the src directory and run commands from the Ionic CLI.

cd src
ionic

eg:
ionic serve --lab --port 4000 -r

You will need to make sure the NSIS path is added as an environment variable:

setx PATH "%PATH%;C:\Program Files (x86)\NSIS"
