}

/*
<FormGroup>

index.js代码如下:
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import * as serviceWorker from './serviceWorker';
import { Provider } from "mbox-react";
import AppState from './store/AppState';

ReactDOM.render(

<Provider store = {AppState}><App /></Provider>

, document.getElementById('root'));

// If you want your app to work offline and load faster, you can change
// unregister() to register() below. Note this comes with some pitfalls.
// Learn more about service workers: http://bit.ly/CRA-PWA
serviceWorker.unregister();

package.json代码如下:
{
"name": "client",
"version": "0.1.0",
"private": true,
"dependencies": {

"bootstrap": "^4.0.0",
"jquery": "^3.3.1",

你期待的结果是什么？实际看到的错误信息又是什么？

希望能执行inject运行成功

Answer 1

这个 observer 你有从 mobx-react 中引入，但是你的 inject 没有引入，所以报了 inject未定义这个错误。
建议引入一下：import { observer, inject } from "mobx-react";
