Question

我将我的React版本升级到56，我已经完成了干净的设置。现在我正面临这个问题，我不知道如何解决。

我什至安装了此https://www.npmjs.com/package/babel-preset-react-native。

error: bundling failed: Error: Cannot find module 'metro-react-native-babel-preset' from 'D:\React\Snap'

package.json

{
  "name": "SnapHaber",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest"
  },
  "dependencies": {
    "react": "16.3.1",
    "react-native": "^0.56.0",
    "react-native-firebase": "^4.3.0"

    "babel-jest": "23.2.0",
    "babel-preset-react-native": "^5.0.2",

    "react-test-renderer": "16.3.1"
  },
  "jest": {
    "preset": "react-native"
  }
}

.babelrc

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

在npm之后，我会执行metro-react-native-babel-preset --save-dev：

   Loading dependency graph, done.
