尝试使用 inversify 将接口绑定到实现时，出现引用错误

Question

我正在使用 inversify 创建一个 ioc 容器。

import { Container } from 'inversify';
import { coreIocSymbols } from './iocsymbols';

import { IHttpService, IUsersService, } from '../interfaces';
import {Api, UsersService} from '../services';


const coreIocContainer = new Container();

coreIocContainer.bind<IHttpService>(coreIocSymbols.IHttpService).to(Api);
coreIocContainer.bind<IUsersService>(coreIocSymbols.IUsersService).to(UsersService);

export { coreIocContainer };

在这条线上：

coreIocContainer.bind<IUsersService>(coreIocSymbols.IUsersService).to(UsersService);

我得到：

Uncaught ReferenceError: can't access lexical declaration 'UsersService' before initialization

但是我不明白，因为这个 class 是在我从中导入的文件中定义的：

import { inject, injectable } from 'inversify';
import { currentUser, coreIocSymbols } from '../infrastructure';
import { IHttpService, IUser, IUsersService } from '../interfaces';

@injectable()
export class UsersService implements IUsersService {
  constructor(
    @inject(coreIocSymbols.IHttpService) private readonly api: IHttpService
  ) {}

  async getCurrent(): Promise<IUser> {
    const response = await this.api.get<IUser>('/users/current');

    currentUser.set(response.data);
    return response.data;
  }
}
