用笑话,巴别塔,网页和反应测试。当前未启用对实验语法“classProperties”的支持

好吧,我有一个巨大的问题,试图启用笑话我的反应原生应用程序。本主题的每个答案都为我的webpack或package.json提供了不同的配置。我希望能在这里找到答案。

对于这个简单的测试:

import 'react-native';
import React from 'react';
import Index from '../index.ios.js';

// Note: test renderer must be required after react-native.
import renderer from 'react-test-renderer';

it('renders correctly', () => {
  const tree = renderer.create(
    <Index />
  );
});

我跑: npm test 获得:

D:\workspaces\web\react\site\node\u modules\react native\jest\mockComponent.js: 目前还不支持实验语法“classProperties” 启用(20:24):

有一个可爱的解决方案:

https://git.io/vb4SL 您的Babel配置的“plugins”部分来启用转换。

这是我的package.json配置:
