Question

我将我的react native应用程序从0.48.3升级到0.59.8，一切正常，直到启动模拟器。然后出现此错误：

   error: bundling failed: Error: Unable to resolve module 
   `@babel/runtime/helpers/interopRequireDefault` from 
    `E:\als\variant\generic\index.android.js`: Module 
    `@babel/runtime/helpers/interopRequireDefault` does not exist in the 
    Haste module map

这是我的Package.json：

  "dependencies": {
  "@babel/polyfill": "^7.4.4",
  "@babel/runtime": "^7.0.0-beta.55",
   "babel-loader": "^8.0.5",
   "content-disposition": "^0.5.2",
   "core-js": "^3.0.1",
   "react": "16.8.6",
   "react-dom": "16.8.6",
   "react-loader": "^2.4.5",
   "react-native": "0.59.8",
   "react-redux": "^5.0.6",
    "react-router-dom": "^5.0.0",
    "redux": "^3.7.2",
   "redux-thunk": "^2.2.0",

},
 "devDependencies": {
   "@babel/plugin-proposal-class-properties": "^7.4.4",
  "@babel/plugin-proposal-decorators": "^7.4.4",
  "@babel/plugin-proposal-nullish-coalescing-operator": "^7.4.4",
  "@babel/plugin-transform-block-scoping": "^7.0.0",
  "@babel/plugin-transform-flow-strip-types": "^7.4.4",
   "@babel/plugin-transform-react-jsx-source": "^7.2.0",
   "@babel/plugin-transform-runtime": "^7.4.4",
   "@babel/preset-env": "^7.4.3",
    "@babel/preset-flow": "^7.0.0",
    "@babel/preset-react": "^7.0.0",
      "babel-eslint": "^10.0.1",
     "babel-jest": "^24.8.0",
    "babel-preset-react-native": "^5.0.2",
 }

我已经尝试了所有在类似问题中找到的解决方案，但是都无法正常工作。请问您有什么想法吗？

Answer 1

在您的依赖项中看不到运行时

npm install --save @babel/runtime

此外，尝试使用重置缓存

npm run start --reset-cache

Answer 2

我也遇到了同样的问题，在线程上没有提到解决方案。但是我终于能够通过删除并重新安装react-native的全局版本来解决它：

npm uninstall react-native -g
npm install react-native@latest -g

然后我重新运行该错误时消失了：

react-native start

React Native-无法解析模块`@ babel / runtime / helpers / interopRequireDefault`
