我在单一水疗中心网站上查看了如何创建包裹的信息，但遇到了例外情况

Question

我一直在尝试实现单spa包裹，但遇到了以下例外情况

index.js:167 Uncaught (in promise) Error: During 'mount', parcel threw an error: 
                  <Parcel /> was not passed a mountParcel prop, nor is it rendered where mountParcel is within the React context.
                  If you are using <Parcel /> within a module that is not a single-spa application, you will need to import mountRootParcel from single-spa and pass it into <Parcel /> as a mountParcel prop   

    at index.js:167
    at index.js:114

该错误是关于其mountParcel属性向下传递到包裹的，我已经从单spa库中提取了它，但是仍然遇到相同的问题，我已经在这个问题上作了一段时间了，请协助

请在下面找到我的代码

parcel-config.js

// myParcel.js
import React from 'react'
import ReactDOM from 'react-dom';
import singleSpaReact from 'single-spa-react'

import MyParcelComponent from './my-parcel-component.component';

export const MyParcel = singleSpaReact({
  React,
  ReactDOM,
  rootComponent: MyParcelComponent
})

export function bootstrap(props) {
  return MyParcel.bootstrap(props).then(res => {
    debugger;
  });
}

export function mount(props) {
  return MyParcel.mount(props);
}

export function unmount(props) {
  return MyParcel.unmount(props);
}

// in this case singleSpaReact is taking our inputs and generating an object with the required lifecycles.

MyParcelComponent.js

import React from 'react';

export default class MyParcelComponent extends React.Component {
  render() {
    return (
      <div >
        <h1>This is a parcel</h1>
      </div>
    );
  }
}

单spa应用程序。尝试消耗包裹

import React from 'react';
import Parcel from 'single-spa-react/parcel'
import * as singleSpa from 'single-spa';

import  { MyParcel } from './parcel1/parcel-config';

export default class Root extends React.Component {

  componentWillMount(){
    console.log(singleSpa);
  }
  render() {
    return (
      <div style={{ marginTop: '100px' }}>
        This was rendered by app 1, which is written in React.

        <Parcel 
          config={MyParcel}
          mountParcel={singleSpa.mountRootParcel}
          wrapWith="div" />
      </div>
    );
  }
}
