Question

我刚刚生成了React-Native项目，yarn test失败了。

package.json文件中存在

jest-expo预设。

FAIL  ./App.test.js
 ● Test suite failed to run

   /Users/haito/Projects/react-native/TalkToMe/node_modules/react-router-native/main.js:1
   ({"Object.<anonymous>":function(module,exports,require,__dirname,__filename,global,jest){export * from 'react-router'
                                                                                            ^^^^^^

   SyntaxError: Unexpected token export

Test Suites: 1 failed, 1 total

Ran all test suites.

编辑添加的babel预设：

 FAIL  ./App.test.js
  ● Test suite failed to run

Jest测试失败的意外导出反应原生
