"You require appropriate loaders", Using react native and expo. App fails to compile on the web, but runs on android

I'm using react native expo. The app works fine on android, but when run on the web gets a compilation error. It was working fine in before, but I suspect this started after installing some new package.

/ReactNativeFrontend/node_modules/@codler/react-native-keyboard-aware-scroll-view/lib/KeyboardAwareHOC.js 13:12
Module parse failed: Unexpected token (13:12)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders
| } from 'react-native'
| import { isIphoneX } from 'react-native-iphone-x-helper'
> import type { KeyboardAwareInterface } from './KeyboardAwareInterface'
| 
| const _KAM_DEFAULT_TAB_BAR_HEIGHT: number = isIphoneX() ? 83 : 49

My babel config

module.exports = function(api) {
  api.cache(true);
  return {
    presets: ['babel-preset-expo'],
  };
};

This is a native-base library problem. While You are using it's some Components there might error occur. I found that this error is not occurring in 2.11 or it's less version so try to install that specific version

npm install [email protected]

I had this exact same issue, I found a solution today. Thanks to this kind user on the expo forums.

judipuak's post

  1. Install the react-native-keyboard-aware-scroll-view package into your node_modules with yarn on npm
  2. Navigate to native base/dist/src/basic and open Content.js
  3. Find var _reactNativeKeyboardAwareScrollView=require('@codler/react-native-keyboard-aware-scroll-view')
  4. Change this to var _reactNativeKeyboardAwareScrollView=require('react-native-keyboard-aware-scroll-view') (remove the @codler)

Update: Here's a more permanent solution courtesy of patarapolw

I downgrade two things, and upgrade one thing, in package.json

 {
  "dependencies": {
    "native-base": "~2.11",
    "react-native-web": "~0.11"
  },
  "resolutions": {
    "react-native-keyboard-aware-scroll-view": "^0.9.0"
  },
}
