javascript - React Native Jest - BABEL 参考错误

Question

我正在为 Uni 的一个项目开发一个修订应用程序，并且我几乎完成了所有代码，但是现在是测试的时候了，我在为我的 React Native 项目设置测试环境时遇到了一些麻烦。无论我尝试什么，我都会不断收到此错误。我很确定我已经搞砸了一些依赖项的配置，但是几天来一直试图让它工作，只是觉得我需要第二个意见和一组新的眼睛。

这是我不断收到的错误消息；

● Test suite failed to run

    ReferenceError: [BABEL] C:\Users\Owner\Dropbox\Discrete Math Tutor App for FC2\Revision App\FC2 Revision App\src\tests\Main.test.js: Unknown option: base.configFile. Check out http://babeljs.io/docs/usage/options/ for more information about options.

    A common cause of this error is the presence of a configuration options object without the corresponding preset name. Example:

    Invalid:
      `{ presets: [{option: value}] }`
    Valid:
      `{ presets: [['presetName', {option: value}]] }`

    For more detailed information on preset configuration, please see https://babeljs.io/docs/en/plugins#pluginpresets-options.

}

这是我的 babel.config.js 文件；

module.exports = function(api) {
  api.cache(true);
  return {
    presets: ['babel-preset-expo'],
  };
};

这是测试文件；

import React from 'react';
import 'react-native';
import { Main } from '../screens/Main.js';
import { shallow, mount, enzyme, configure } from 'enzyme';

const Adapter = require("enzyme-adapter-react-16");

enzyme.configure({ adapter: new Adapter() });

test('Search snapshot test', () => {
	const component = shallow(<Main />);
	expect(component.change(10)).toBe(100);
});

我将不胜感激任何帮助/建设性的批评（因为我确信我的编码实践不是最好的）！:)
