The issue is that Babel 7.0 and up doesn’t recognize the env preset anymore. just switch it to @babel/preset-env in your .babelrc.

1. Install the new preset:

   npm install @babel/preset-env --save-dev
   

2. Update your .babelrc:

   {
       "presets": [
           "@babel/preset-env"
       ]
   }
   

Try building again
