我正在使用Jest来测试我的React应用程序.

最近,我将DeckGL添加到了我的应用程序中.我的测试因此错误而失败:

Test suite failed to run

/my_project/node_modules/deck.gl/src/react/index.js:21
export {default as DeckGL} from './deckgl';
^^^^^^

SyntaxError: Unexpected token export

  at ScriptTransformer._transformAndBuildScript (node_modules/jest-runtime/build/script_transformer.js:318:17)
  at Object.<anonymous> (node_modules/deck.gl/dist/react/deckgl.js:9:14)
  at Object.<anonymous> (node_modules/deck.gl/dist/react/index.js:7:15)

这似乎是Jest在运行它的测试之前转换节点模块的问题.

这是我的.babelrc:

{
  "presets": ["react", "es2015", "stage-1"]
}

这是我的开玩笑设置:

"jest": {
    "testURL": "http://localhost",
    "setupFiles": [
      "./test/jestsetup.js"
    ],
    "snapshotSerializers": [
      "<rootDir>/node_modules/enzyme-to-json/serializer"
    ],
    "moduleDirectories": [
      "node_modules",
      "/src"
    ],
    "moduleNameMapper": {
      "\\.(css|scss)$": "<rootDir>/test/EmptyModule.js"
    }
  },

我似乎有正确的事情需要改造export {default as DeckGL }.所以任何想法都会出错？
