当我运行npm start babel抛出以下错误：ReferenceError：未知选项：.caller.有关选项的更多信息,请查看 http://babeljs.io/docs/usage/options/.

我的package.json：

{
"private": true,"scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start","test": "jest"
  },"dependencies": {
    "axios": "^0.18.0","moment": "^2.20.1","prop-types": "latest","react": "^16.5","react-native": "^0.57","react-native-material-textfield": "^0.12.0","react-native-material-ui": "^1.30.1","react-native-off-canvas-menu": "^0.1.32","react-native-pull-refresh": "^1.0.0","react-native-size-matters": "^0.1.4","react-native-snackbar": "^0.5.3","react-native-snap-carousel": "^3.7.5","react-native-vector-icons": "^6.0.2","react-navigation": "^2.18.0","react-redux": "^5.0.6","redux": "^4.0.1","redux-persist": "^5.5.0","redux-thunk": "^2.2.0","ree-validate": "^3.0.2"
  },"devDependencies": {
    "@babel/core": "7.0.0-beta.42","babel-jest": "23.6.0","jest": "23.6.0","metro-react-native-babel-preset": "^0.48.1","react-test-renderer": "16.5.2"
  },"jest": {
    "preset": "react-native"
  },"rnpm": {
    "assets": [
      "./src/assets/fonts"
    ]
  }
}

我提到我的项目是反应原生应用程序.
我没有对等依赖项错误.我没有发现不同的babel依赖关系之间的任何冲突.谢谢您的帮助.

解决方法

根据RN 0.57更改日志,您需要：

Ensure that you have all the babel dependencies to version ^7.0.0 (you
may also need to add babel-core”: “7.0.0-bridge.0” as a yarn
resolution to ensure retro-compatibility)

看来你有一个@ babel / core“：”7.0.0-beta.42不是^ 7.0.0.

这是在RN 0.57.1??和0.57.2中为我工作的配置：

还要根据RN change.log检查.babelrc文件.

在任何时候,如果你得到一些babel错误,你可以尝试用这样的东西清理所有缓存(使用纱线或npm,取决于你有什么)：

rm -rf $TMPDIR/react-* && rm -rf $TMPDIR/metro-* && rm -rf $TMPDIR/haste-* && watchman watch-del-all && rm -rf node_modules && yarn install && npm start -- --reset-cache
