无法在typescript中配置Apolloserver的数据源

npm install apollo-server apollo-datasource-rest

import { ApolloDataSource } from 'apollo-datasource';

class MyDataSource extends ApolloDataSource {
  // 实现数据源的具体逻辑
}

import { ApolloServer } from 'apollo-server';
import { MyDataSource } from './myDataSource';

const server = new ApolloServer({
  // 其他配置项...
  dataSources: () => ({
    myDataSource: new MyDataSource(),
  }),
});

import { ApolloDataSource } from 'apollo-datasource';

class MyDataSource extends ApolloDataSource {
  async getUser(id: string) {
    const response = await this.get(`/users/${id}`);
    return response.data;
  }
}

const resolvers = {
  Query: {
    user: async (_, { id }, { dataSources }) => {
      return dataSources.myDataSource.getUser(id);
    },
  },
};
