react-native error: module does not exist in module map

Question

This is the error:

I have tried all of the things in the Github issue, in the error description and in this question, to no avail.

Here is my package.json:

{
  "name": "MyAppName",
  "version": "0.1.0",
  "private": true,
  "devDependencies": {
    "jest-expo": "^24.0.0",
    "react-native-scripts": "1.8.1",
    "react-test-renderer": "16.2.0"
  },
  "main": "./node_modules/react-native-scripts/build/bin/crna-entry.js",
  "scripts": {
    "start": "react-native-scripts start",
    "eject": "react-native-scripts eject",
    "android": "react-native-scripts android",
    "ios": "react-native-scripts ios",
    "test": "node node_modules/jest/bin/jest.js --watch"
  },
  "jest": {
    "preset": "jest-expo"
  },
  "dependencies": {
    "core-js": "^2.5.3",
    "expo": "^24.0.2",
    "react": "^16.2.0",

    "react-navigation": "^1.0.0-beta.22",
    "rn-viewpager": "^1.2.9"
  }
}

FOR ANY FUTURE VIEWERS: This was a dependency issue. If you are using version control, copy your old dependencies into your current package.json

Answer 1

This was a dependency issue. If you are using version control, copy your old dependencies into your current package.json

I couldn't figure out what was wrong so I simply re-cloned my project from GitHub and copied my code over.
