  ERROR in ./src/app.js
  Module build failed: Error: Requires Babel "^7.0.0-0", but was loaded with "6.25.0". If you are sure you have a
   compatible version of @babel/core, it is likely that something in your build process is loading the wrong vers
  ion. Inspect the stack trace of this error to look for the first entry that doesn't mention "@babel/core" or "b
  abel-core" to see what is calling Babel. (While processing preset: "/Users/VIKRANT/Desktop/IndecisionAPP/node_m
