指的是一个值，但在此处用作类型

Question

我是typescript和node.js的新手，我也在尝试使用typescript和node.jsCreateUserDto' refers to a value but is being used as a type here. Did you mean 'typeof CreateUserDto'?我用users.ts的名字创建了一个文件。这是我的模型，也用users.service.ts的名字创建一个文件，你可以在下面找到这些文件的代码。请帮助我，我可以修复这个错误，非常感谢。

错误图像型号：users.ts

import * as mongoose from 'mongoose';
// import IUser from "../interface/users"
import { Schema, Document } from 'mongoose';
export interface IUser extends Document {
firstName: String,
lastName: String,
email: String,
password: String
}
const UserSchema: Schema = new Schema({
firstName: {
type: String,
required: true
},
lastName: {
type: String,
required: true
},
email: {
type: String,
required: true
},
password: {
type: String,
required: true
}
}, {
timestamps: true
});
export default mongoose.model<IUser>('User', UserSchema);

users.service.ts

import UsersDao from '../daos/users.dao';
import { CRUD } from '../../common/interfaces/crud.interface';
import CreateUserDto from "../model/users";
import { PutUserDto } from '../dto/put.user.dto';
import { PatchUserDto } from '../dto/patch.user.dto';
class UsersService implements CRUD {
async create(resource: CreateUserDto) {
return UsersDao.addUser(resource);
}
async deleteById(id: string) {
return UsersDao.removeUserById(id);
}
async list(limit: number, page: number) {
return UsersDao.getUsers();
}
async patchById(id: string, resource: PatchUserDto) {
return UsersDao.patchUserById(id, resource);
}
async readById(id: string) {
return UsersDao.getUserById(id);
}
async putById(id: string, resource: PutUserDto) {
return UsersDao.putUserById(id, resource);
}
async getUserByEmail(email: string) {
return UsersDao.getUserByEmail(email);
}
}
export default new UsersService();

CreateUserDto是mongoose模型，这不是typescript的有效类型描述符。你可以在这里阅读所有有效的ts类型。

你想做的是使用你创建的IUser接口，就像这样：

async create(resource: IUser) {
return UsersDao.addUser(resource);
}
