javascript 下一个路由server.js失败：类型错误：routes.getRequestHandler不是函数

我在server.js中遇到一个错误。我的脚本如下所示：

const { createServer } = require('http');
const next = require('next');
const routes = require('./routes');

const app = next ({
  dev: process.env.NODE_ENV !== 'production'
});

const handler = routes.getRequestHandler(app);

app.prepare().then( () =>{
  createServer(handler).listen(3000, (err) => {
    if (err) throw err;
    console.log('Ready on localhost:3000');
  });
});

它几乎是直接从next-routes文档中复制出来的。这是我运行〉npm run dev时得到的结果

C:\Users\zangezi39\kickstart\server.js:9

const handler = routes.getRequestHandler(app);
                ^

必须更改routes.js脚本
请检查const routes = require('next-routes');是否更改为const routes = require('next-routes')();

不是那样，看看这个

const next = require('next');
const dev = process.env.NODE_ENV !== 'production';
const app = next({ dev });

const handler = app.getRequestHandler();

您只是在该行的末尾忘记了一个,。
下面是适合我的代码：

const {createServer} = require('http');
    const next = require('next');

    const app = next({
     dev: process.env.NODE_ENV !== 'production',
    });

    const routes = require('./routes');
    const handler = routes.getRequestHandler(app);

    app.prepare().then(() => {
      createServer(handler).listen(3000, (err) => {
       if (err) throw err;
         console.log('Ready on localhost: 3000');
      });
    });

我有同样的错误，当routes.js与server.js处于同一级别时，我修复了该错误，此外，您还应确保routes.js如下所示

const routes = require('next-routes')();
module.exports = routes

许多程序员忘记在最后导出routes模块，因此您应该在routes.js中包含'module.exports = routes'。另外，转到package.json文件并检查是否安装了next和next-routes模块

确保在routes.js文件中的const routes = require（“next-routes”“'（）'末尾添加'（）'
