Question

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

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",

    "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"
    ]
  }
}

我提到我的项目是一个本机应用程序。我没有对等依赖性错误。我找不到不同的babel依赖项之间的任何冲突。谢谢您的帮助。

根据RN 0.57更改日志，您需要：

确保对版本^ 7.0.0拥有所有babel依赖项（您可以可能还需要添加babel-core“：” 7.0.0-bridge.0“作为纱线分辨率以确保具有逆向兼容性）

似乎您有@babel/core": "7.0.0-beta.42而不是^7.0.0。

以下是适用于RN 0.57.1和0.57.2的配置： https://stackoverflow.com/a/52717426/1979861

还要检查.babelrc文件是否符合RN change.log。

在任何时候，如果您遇到一些babel错误，您都可以尝试使用类似以下方法清除所有缓存（使用yarn或npm，具体取决于您拥有的东西）：

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
