react-native - 预设选项中不允许 Babel 覆盖反应原生导航

问题描述

我试图在react-native上添加一个路由器react native navigation v2到这个启动项目，但我有一个与 babel 包有关的问题（可能）。当我跑

react-native run-android

我在 Metro Bundler 中有这个错误：

加载依赖图，完成。: 捆绑失败: 错误: [BABEL] D:\react—native\projecti\index.js: .overr ides is not allowed in preset options

在 Object.keys.forEach.key (D:\react—native\projecti\node_modules\metro\node odules\Obabel\core\lib\config\validation\options.js:71:13) at Array.forEach () at在 instantiatePreset (D:\react—native\projecti\node_modules\metro\ node_modul s\l@babel\core\lib\config\full.js:242:36) at cachedFunction (D:\react—native\projecti\node_modules\metro\node_modules\ babel\core\lib\config\caching.js :42:19) 在 loadPresetDescriptor (D:\react-native\projecti\node_modules\metro\node_mo Iules\ftabel\core\lib\config\full.js:233:45) 在 config.presets.map.descriptor (D :\react—native\projecti\node_modules\metr I\node_modules\ftabel\core\lib\config\full.js:68:19) at Array.map () at recurseDescriptors (D:\react—native\projecti\node_modules\metro\node_modu les\Obabel\core\lib\config\full.js:66:38）

在控制台中构建成功结束。

解决方案

看起来你有 RN 0.56，它使用了一些 babel 的 beta 版本。

我看到你有2个解决方案：

1) 保持 RN 0.56 并设置正确的 babel deps

对于 RN 0.56，您需要确保所有 @babel/* deps 都固定在 7.0.0-beta.47 版本（请参阅 0.56 的更改日志）

2) 将您的项目升级到 RN 0.57

为了能够使用最新的 babel 7 依赖项，您必须将您的项目迁移到 RN 0.57。

This is what I have for a 0.57.1 project:

"dependencies": {
    "react": "16.5.0",
    "react-native": "0.57.1",
    .......
  }

  "devDependencies": {
    "@babel/core": "^7.0.0",
    "@babel/plugin-proposal-class-properties": "^7.0.0",
    "@babel/plugin-proposal-decorators": "^7.0.0",
    "@babel/plugin-proposal-do-expressions": "^7.0.0",
    "@babel/plugin-proposal-export-default-from": "^7.0.0",
    "@babel/plugin-proposal-export-namespace-from": "^7.0.0",
    "@babel/plugin-proposal-function-bind": "^7.0.0",
    "@babel/plugin-proposal-function-sent": "^7.0.0",
    "@babel/plugin-proposal-json-strings": "^7.0.0",
    "@babel/plugin-proposal-logical-assignment-operators": "^7.0.0",
    "@babel/plugin-proposal-nullish-coalescing-operator": "^7.0.0",
    "@babel/plugin-proposal-numeric-separator": "^7.0.0",
    "@babel/plugin-proposal-object-rest-spread": "^7.0.0",
    "@babel/plugin-proposal-optional-chaining": "^7.0.0",
    "@babel/plugin-proposal-pipeline-operator": "^7.0.0",
    "@babel/plugin-proposal-throw-expressions": "^7.0.0",
    "@babel/plugin-syntax-dynamic-import": "^7.0.0",
    "@babel/plugin-syntax-import-meta": "^7.0.0",
    "@babel/plugin-syntax-object-rest-spread": "^7.0.0",
    "@babel/plugin-transform-runtime": "^7.0.0",
    "@babel/preset-env": "^7.0.0",
    "@babel/preset-flow": "^7.0.0",
    "@babel/register": "^7.0.0",
    "babel-core": "^7.0.0-bridge.0",
    "babel-preset-react-native-stage-0": "^1.0.1",
    .....

}

重要：.babelrc将配置更新为：

{
    "presets": ["module:metro-react-native-babel-preset"]
}
