升级到0.57.1​​时反应不佳

Question

im将我的react native项目从0.54.6升级到0.57.1​​，并在我的pckager中给出此错误

这是我的package.json

Loading dependency graph, done.
error: bundling failed: Error: The 'decorators' plugin requires a 'decoratorsBeforeExport' option, whose value must be a boolean. If you are migrating from Babylon/Babel 6 or want to use the old decorators proposal, you should use the 'decorators-legacy' plugin instead of 'decorators'.

这是我的.babelrc外观

  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest"
  },
  "dependencies": {
    ...
    "babel-plugin-transform-decorators-legacy": "^1.3.4",
    "react": "16.0.0-beta.5",
    "react-native": "^0.55.4",
    ...
  },
  "devDependencies": {
    "babel-jest": "21.2.0",
    "babel-preset-react-native": "^4.0.0",

  },

    "preset": "react-native"
  },
  "rnpm": {
    "assets": [
      "./assets/fonts/"
    ]
  }
}

我尝试安装最新版本的babel，但我不确定那是否可行或我是否正确

我的项目成功构建，但是我的打包程序没有加载到最后，并因该错误而卡住

感谢前进。
