Express 网页包开发服务器语法错误：意外令牌<；在JSON中的位置0

我有一个多页的react应用程序，运行时打开了webpack。 当我运行

webpack dev server--hot--inline

并转到

http://localhost:3000/movies

，我的组件不呈现，控制台显示

bundle.js:17 SyntaxError: Unexpected token < in JSON at position 0
    at Object.<anonymous> (http://localhost:3000/bundle.js:1:47124)
    at w (http://localhost:3000/bundle.js:33:9889)
    at Generator._invoke (http://localhost:3000/bundle.js:33:9677)
    at Generator.e.(anonymous function) [as next] (http://localhost:3000/bundle.js:33:10068)
    at i (http://localhost:3000/bundle.js:1:47400)
    at a (http://localhost:3000/bundle.js:1:47495)
    at <anonymous>

我不知道这是否只是一个json问题，react应用程序没有直接“需要”。json文件，它正在从节点请求一个json响应。

react执行

fetch

实际上得到了一个html响应

json.parse（'
const path = require('path');

const package = require('./package.json');

const PATHS = {
    src: path.join(__dirname, './src'),
    public: path.join(__dirname, './public')
