无法在我的Vue项目中创建有效的版本，“找不到相对模块”错误

Question

我正在使用npm run build构建一个Vue项目。

当我将结果（根据这个问题的答案：How to deploy Vue app?的结果（index.html和dist文件夹）上载到ec2实例时，出现错误：

ERROR  Failed to compile with 1 errors                                                                                                                                                           4:58:08 PM
