apollo - 无法使用 @graphql-tools/merge 使用合并的 typeDefs 和解析器运行 apollo-server-express

Question

嘿朋友这是我的项目和文件的结构如下：

从app.js文件开始：

import { Server } from "./src/Server";
import { config } from "dotenv";

config();

Server.StartServer();

下面是Server.ts引导 apollo-server-express 的文件

import express from "express";
import http from "http";
import { ApolloServer } from "apollo-server-express";
import { GraphQLServerOptions } from "apollo-server-core/src/graphqlOptions";
import { schema } from "./graphql/index";

export class Server {
  public static StartServer() {
    const app: express.Application = express();
    const server = new ApolloServer({
      schema,
      graphiql: true,
    } as unknown as GraphQLServerOptions);
    server.applyMiddleware({ app });
    const httpServer = http.createServer(app);
    server.installSubscriptionHandlers(httpServer);

    httpServer.listen(process.env.PORT, function () {
      console.log(`server is running on port ${process.env.PORT}`);
    });
  }
}

这是user.resolvers.ts我的解析器放在这里的文件：

import { IResolvers } from "graphql-tools";

export const resolver: IResolvers = {
  Mutation: {
    register: function (parent, args, content, info) {
      console.log(parent);
    },
  },
  Query: {
    getUser: function (parent, args, content, info) {
      console.log(parent);
    },
  },
};

在这里，我们使用 inuser.schema.ts文件的 typeDef：

import { gql } from "apollo-server-express";
export const typeDef = gql`
    type User {
        username: String
        password: String
    }

    type Mutation {
        register(input: {username: String!, passwprd: String!})
    }

    type Query {
        getUSer(username): User
    }
`;

最后在./src/graphql/index.ts文件中我正在为解析器和 typeDefs 进行合并，我正在制作 executableSchema 以将其添加到 ApolloServer 配置对象，但我面临以下错误：

任何想法和建议将不胜感激。早期感谢贡献者:)
