reactjs - Babel 未知选项 : . 调用者

Question

当我运行 npm start babel 时抛出以下错误:ReferenceError: Unknown option: .caller。查看http://babeljs.io/docs/usage/options/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",
    "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",

    "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"
    ]
  }
}

我提到我的项目是一个 react native 应用程序。我没有对等依赖错误。我没有发现不同 babel 依赖项之间有任何冲突。感谢您的帮助。

根据 RN 0.57 变更日志，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)

您似乎拥有 @babel/core": "7.0.0-beta.42 而不是 ^7.0.0。

以下是在 RN 0.57.1​​ 和 0.57.2 中对我有用的配置: https://stackoverflow.com/a/52717426/1979861

同时检查 .babelrc 文件是否符合 RN change.log。

在任何时候，如果你遇到一些 babel 错误，你都可以尝试用这样的东西清理所有缓存(使用yarn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
