问题分析

步骤有点啰嗦，犯错的原因其实就很简单，就是没有把要导入的文件名写全，所有就报如下没有找到对应文件的错误。

Error [ERR_MODULE_NOT_FOUND]: Cannot find module ‘d:\Project_Files\VSCode_Projects\React_Learning\《React全栈》\第1章\ES6语言特性\e7_Modules\test’ imported from d:\Project_Files\VSCode_Projects\React_Learning\《React全栈》\第1章\ES6语言特性\e7_Modules\main.js

需求

想要在main.js文件下导入test.js文件导出的模块对象与变量

解决问题

在VSCode的右键到对应的终端

到终端输入命令npm init -y新建package.json文件

加入 “type”:“modules”

修改导入的文件名
main.js

最终输出结果为：
