在JavaScript文件中通过import引入公共模块，然后就报错

​​原文：读心悦​​ 在JavaScript文件中通过import引入公共模块，然后就报错了：

PS D:\code\JavaScript\js> node .\bubbleSort.js
(node:18356) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
(Use `node --trace-warnings ...` to show where the warning was created)
D:\code\JavaScript\js\bubbleSort.js:9
import {arr} from "./array-data.js";
^^^^^^

SyntaxError: Cannot use import statement outside a module

解决这类异常方式是：首先确保当前的环境已经安装了node，然后用命令执行​​npm init -y​​生成package.json文件。

最后修改一下：添加一下​​"type": "module",​​
