inversify-binding-decorators失败，文件分开 warrior.ts： weapon.ts： main.ts：

如何解决inversify-binding-decorators失败，文件分开 warrior.ts： weapon.ts： main.ts：

以下代码运行良好，直到我将其分离到其他文件中为止：

import {Container,inject} from "inversify";
import {buildproviderModule,provide} from "inversify-binding-decorators";
import "reflect-Metadata";

export interface Weapon {
    hit(): string
}

@provide("Weapon")
export class Katana implements Weapon {
    public hit() {
        return "cut!";
    }
}

@provide(Ninja)
export class Ninja {
    private weapon: Weapon;

    constructor(@inject("Weapon") weapon: Weapon) {
        this.weapon = weapon;
    }

    fight() {
        return this.weapon.hit()
    }
}


try {
    const container = new Container();
    container.load(buildproviderModule());
    const ninja = container.get(Ninja);

    console.log(ninja.fight())
    console.log("success")
} catch (e) {
    console.error(e)
}

console.log("done")

重构后，这是新的文件结构：

ioc/
    node_modules/
    src/
        warrior.ts
        weapon.ts
    main.ts
    package.json
    package-lock.json
    tsconfig.json

它们具有相同的逻辑，只是分开了：

warrior.ts：

import "reflect-Metadata";
import {provide} from "inversify-binding-decorators";
import {inject} from "inversify";
import {Weapon} from "./weapon";

@provide(Ninja)
export class Ninja {
    private weapon: Weapon;

    constructor(@inject("Weapon") weapon: Weapon) {
        this.weapon = weapon;
    }

    fight() {
        return this.weapon.hit()
    }
}

weapon.ts：

import {provide} from "inversify-binding-decorators";

export interface Weapon {
    hit(): string
}

@provide("Weapon")
export class Katana implements Weapon {
    public hit() {
        return "cut!";
    }
}

main.ts：

import {Container} from "inversify";
import {buildproviderModule} from "inversify-binding-decorators";
import "reflect-Metadata";
import {Ninja} from "./src/warrior";

try {
    const container = new Container();
    container.load(buildproviderModule());
    const ninja = container.get(Ninja);

    console.log(ninja.fight())
    console.log("success")
} catch (e) {
    console.error(e)
}

console.log("done")

但是现在它在const ninja = container.get(Ninja);上失败，错误为Error: No matching bindings found for serviceIdentifier: Weapon。

知道什么问题吗？
