Svelte(汇总)- 错误 : Unexpected token (Note that you need @rollup/plugin-json to import JSON files)

Question

我正在做 没有 来触发此错误。该应用程序前一秒运行良好，下一秒就不行了。
为什么会这样？这不是由于缺少 @rollup/plugin-json 插件，因为它以前没有它就可以工作。

添加插件

npm i @rollup/plugin-json --save-dev

rollup.js.config

import json from "@rollup/plugin-json";

export default {
    plugins: [
        commonjs(),
        json(),      // <---- put after commonjs
    ]
}

客户端错误

Uncaught ReferenceError: require$$0$1 is not defined
    at main.js:5
(anonymous) @ main.js:5

Answer 1

问题是由于自动完成，我正在客户端中导入节点模块。

import { is } from "express/lib/request";
