node运行含有ES6语法的js文件
当使用node运行以下代码时
import { Node, LinkedList } from "./07.js"
node index.js
会报错提示:
Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
错误:加载ES模块,设置"type": "module" 在packahejson中或使用.mjs文件
在packahejson中设置"type": "module"
先创建package.json,在package.json中加入"type": "module"
npm init
package.json
{ "name": "js", "version": "1.0.0", "description": "", "main": "00-test.js", "type": "module", // 加入这句 "scripts": { "test": "echo \"Error: no test specified\" && exit 1" }, "author": "", "license": "ISC" }
