import js 模块时遇错

错误详细信息

Access to script at 'xxx' from origin 'null' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https.

解决办法

在本地搭建一个server，通过url地址访问测试文件。
我整理了三个搭建方法：http-server实现server，serve实现server，编码实现server。
三个方法均使用Node.js。安装Node.js方法略。
