Unable to resolve "../../App" from "node_modules/expo/AppEntry.js"

Question

I am making a vue-native app with expo. when upgrading to expo version 33 I get the following error "Unable to resolve "../../App" from "node_modules/expo/AppEntry.js". The need to upgrade to version 33 is because I need the expo filesystem module.

I have already made a new project from scratch and the same error still occurs.

package.json

{
  "main": "node_modules/expo/AppEntry.js",
  "scripts": {
    "start": "expo start",
    "android": "expo start --android",
    "ios": "expo start --ios",
    "web": "expo start --web",
    "eject": "expo eject"
  },
  "dependencies": {
    "expo": "^33.0.0",
    "global": "^4.4.0",
    "react": "16.8.3",

}

I ran into this problem too. I used the expo cli to make the project which sets up your app.json file with "entryPoint": "node_modules/expo/AppEntry.js". AppEntry.js tries to default import from a js file called App in the root directory. Make sure you have a file called App.js|.tsx that default exports a react component.
