反应水合物TypeError:__webpack_require __。i(...)不是函数

门农尼拉

尝试在index.js中使用hydra()时,出现webpack TypeError。当我使用ReactDOM.render()而不是水合物,并且我将水合物用于服务器端渲染时,看不到该错误。

src / index.js

import React from 'react';
import ReactDOM, { hydrate } from 'react-dom';
import { Provider } from 'react-redux';
import App from './App';
import store from './store/configureStore';

hydrate(
  <Provider store={store}>
    <App />
  </Provider>,
  document.getElementById('root')
)
