Babel overrides is not allowed in preset options react native navigation

问题

I trying to add a router react native navigation v2 to this starter project on react-native, but I have a problem that is connected with babel package (probably). When I run

react-native run-android

I have this error in Metro Bundler:

loading dependency graph, done. : bundling failed: Error: [BABEL] D:\react—native\projecti\index.js: .overr ides is not allowed in preset options

It seems that you have RN 0.56 which used some beta versions of babel.

I see you have 2 solutions:

1) Keep RN 0.56 and set correct babel deps

For RN 0.56 you need to ensure all the @babel/* deps are fixed at version 7.0.0-beta.47 (Please see the change log of 0.56 for those)

2) Upgrade your project to RN 0.57

To be able to use latest babel 7 dependencies you will have to migrate your project to RN 0.57.

This is what I have for a 0.57.1 project:

"dependencies": {
    "react": "16.5.0",
    "react-native": "0.57.1",
    .......
  }

  "devDependencies": {
    "@babel/core": "^7.0.0",
    "@babel/plugin-proposal-class-properties": "^7.0.0",
    "@babel/plugin-proposal-decorators": "^7.0.0",
    "@babel/plugin-proposal-do-expressions": "^7.0.0",
    "@babel/plugin-proposal-export-default-from": "^7.0.0",
    "@babel/plugin-proposal-export-namespace-from": "^7.0.0",
    "@babel/plugin-proposal-function-bind": "^7.0.0",
    "@babel/plugin-proposal-function-sent": "^7.0.0",
    "@babel/plugin-proposal-json-strings": "^7.0.0",
    "@babel/plugin-proposal-logical-assignment-operators": "^7.0.0",
    "@babel/plugin-proposal-nullish-coalescing-operator": "^7.0.0",
    "@babel/plugin-proposal-numeric-separator": "^7.0.0",
    "@babel/plugin-proposal-object-rest-spread": "^7.0.0",
    "@babel/plugin-proposal-optional-chaining": "^7.0.0",
    "@babel/plugin-proposal-pipeline-operator": "^7.0.0",
    "@babel/plugin-proposal-throw-expressions": "^7.0.0",
    "@babel/plugin-syntax-dynamic-import": "^7.0.0",
    "@babel/plugin-syntax-import-meta": "^7.0.0",
    "@babel/plugin-syntax-object-rest-spread": "^7.0.0",
    "@babel/plugin-transform-runtime": "^7.0.0",
    "@babel/preset-env": "^7.0.0",
    "@babel/preset-flow": "^7.0.0",
    "@babel/register": "^7.0.0",
    "babel-core": "^7.0.0-bridge.0",
    "babel-preset-react-native-stage-0": "^1.0.1",
    .....

}

Important: update .babelrc configuration to:

{
    "presets": ["module:metro-react-native-babel-preset"]
}

Note: make sure you remove all node_modules and re-install them and clean local cache after babel versions modifications.
