javascript - TS4060 : Return type of exported function has or is using private name 'class'

Question

我被困在这里。 Typescript 一直在提示:

TS4060: Return type of exported function has or is using private name 'class' Student

测试.ts

export default  function MODULETOEXPORT(GreetingIntroTxt:string) {

    class Student {
        name: string;

        constructor(name: string) {
            this.name = name;
        }

        greet() {
            return `"${GreetingIntroTxt}, " + this.greeting`;
        }
    }

    class Teacher {
        name: string;

        constructor(name: string) {
            this.name = name;
        }

        greet() {
            return `"${GreetingIntroTxt}, " + this.greeting`;
        }
    }
    class Professor {
        name: string;

        constructor(name: string) {
            this.name = name;
        }

        greet() {
            return `"${GreetingIntroTxt}, " + this.greeting`;
        }
    }
    return {Professor, Student, Teacher}
}

虽然我在 Typescript Playground 上复制粘贴完全相同的代码，我没有收到任何错误，并且可以完美编译。

重现:

用法.ts

console.log('hello world app')
import module from './test';
const moduleES = module('Holla')
const moduleFR = module('Salut')
const moduleEN = module('Hello')

const greeterESStudent = new moduleES.Student("world");
console.log(greeterESStudent.greet())

const greeterFRStudent = new moduleES.Student("world");
console.log(greeterFRStudent.greet())


const greeterESTeacher= new moduleFR.Teacher("world");
console.log(greeterESTeacher.greet())

const greeterFRTeacher= new moduleFR.Student("world");
console.log(greeterFRTeacher.greet())

Answer 1

您应该将私有(private)成员设为公开。没有办法解决这个问题。
如果您使用来自另一个模块的非导出类型，则会引发类似情况。
