使用apollo-server-express时出现TypeError: graphql_1.isDefinitionNode不是函数

问题详情 #

• 跟着《Pro MERN Stack 第2版》编写代码，在GitCMD中触发错误：TypeError: (0, graphql_1.isDefinitionNode) is not a function
• 纯Express基础代码能正常运行，但加入Apollo Server相关逻辑后就出现该错误
• 试过StackOverflow上的常规解决方案，因为用的是apollo-server-express所以没解决；也尝试过安装apollo-server-express（^{3.11.1）和`graphql`（}0.13.2）的新旧版本，问题仍存在

报错的完整代码 #

const express = require('express');
const { ApolloServer } = require('apollo-server-express');
let aboutMessage = "Issue Tracker API v1.0";

const typeDefs = `
    type Query {
        about: String!
    }
    type Mutation {
        setAboutMessage(message: String!): String
    }
`;

const resolvers = {
    Query: {
        about: ()=> aboutMessage,
    },
    Mutation: { 
        setAboutMessage,       
    },
};

function setAboutMessage(_, { message }) {
    return aboutMessage = message;
}

const server = new ApolloServer({
    typeDefs,
    resolvers
});

const app = express();

app.use(express.static('public'));

server.applyMiddleware({ app, path: '/graphql' });

app.listen(3000, function () {
    console.log('App started on port 3000');
});

可正常运行的基础Express代码 #

const express = require('express');

const app = express();

app.use(express.static('public'));

app.listen(3000, function () {
    console.log('App started on port 3000');
});
