我有例外：

My answer refers to Typescript 2+.
我的回答是指 Typescript 2+。
// 1.ts
export const AdminUser = { ... }
// index.ts
import * as users from './docs/users/admin';
var adminUser = users.AdminUser;
The only difference b/w your code & mine is the * operator in the import statement.
您的代码和我的代码的唯一区别是导入语句中的 * 运算符。
