我无法呈现 React 服务器端。我总是得到^

参考错误：文档未定义

var root = document.getElementById('root');

我知道节点不理解浏览器文档对象是怎么回事。但我似乎无法修复它。我在 webpack、服务器或 app.js 中做错了什么吗？

这是我的代码

服务器.js

import express from 'express';
import path from 'path';
import React from 'react';
import { renderToString } from 'react-dom/server';
import { StaticRouter } from 'react-router-dom';
import { Provider } from 'react-redux';
import configureStore from './src/store/configureStore';
import routes from './src';

const app = express();

app.use(express.static(path.join(__dirname, 'build')));

/**

app.get('/*', function(req, res) {

lib/auth.ts:44:47 - error TS1109: Expression expected.

44     return <WrappedComponent {...this.props} />;
                                                 ~

lib/auth.ts:44:48 - error TS1109: Expression expected.

44     return <WrappedComponent {...this.props} />;

**这是我下面的React HOC组件的代码**

import * as React from 'react';
import Router from 'next/router';
import { NextContext } from 'next';
import nextCookie from 'next-cookies';
import { MOVED_TEMPORARILY } from …
