I had upgraded ionic with npm install -g ionic to the latest version 3.10.3.
Soon my build stop working because some version issues like I need angular 4.1.3, etc.
After I fixed those issues and everything got “compiled”, I notice that my command:
ionic serve or ionic cordova run android --device reports that the build is complete but really it doesn’t run the project.
As you can see in the console log it doesn’t run the serve. I also notice that my www/build folder which should content all the project build is empty. Which means that the script is failing silence and the project doesn’t run.
But I can get the project to create the build by using ‘ionic build --aot’ but as soon I try to run the project using ‘ionic serve’ it clean the folder again back to where I started 
please help
folder www/build
[vns@betito lean2]$ ls www/build/
polyfills.js sw-toolbox.js
