我在 react native 中遇到未捕获的参考错误，为什么会这样？我能够成功构建，但捆绑器显示此错误。我该如何解决？

  "jest": {

  }
}

.babelrc :

{
  "presets": ["module:react-native"]
}
2个回答

在 .bablerc 中包含 react-native 的预设或从 babel.config.js 导出预设，如下所示

module.exports = { presets: ['module:metro-react-native-babel-preset'], plugins: [ '@babel/plugin-transform-runtime' ], }

如有疑问，请使用react-native-cli创建一个新的 ReactNative 项目，并查看构建文件。我就是这样做的，这就是我所拥有的：

包.json

{
  "name": "someproject",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest"
  },
  "dependencies": {
    "react": "16.5.0",
    "react-native": "0.57.1"
  },
  "devDependencies": {
    "babel-jest": "23.6.0",
    "jest": "23.6.0",
    "metro-react-native-babel-preset": "0.47.1",
    "react-test-renderer": "16.5.0"
  },
  "jest": {
    "preset": "react-native"
  }
}

.babelrc : 

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

请注意，如果您更改了 package.json，则可能需要先进行一些清理
