graphql - 运行 apollo-server 时获取节点 "Error: Cannot find module ' core-js/proposals/array-flat-and-flat-map'"

Question

apollo-server-Getting started

我正在使用上面的链接在我的系统中进行 apollo-server 设置。当我尝试使用 node index.js 运行节点文件时。我遇到以下错误:

internal/modules/cjs/loader.js:611
    throw err;
    ^
Error: Cannot find module 'core-js/proposals/array-flat-and-flat-map'
    at Function.Module._resolveFilename 
(internal/modules/cjs/loader.js:609:15)
    at Function.Module._load (internal/modules/cjs/`loader.js:535:25`)
    at Module.require (internal/modules/cjs/`loader.js:663:17`)
    at require (internal/modules/cjs/`helpers.js:20:18`)
    at Object.<anonymous> (E:\`GraphQLApolloServer`\node_modules\`apollo-
env`\lib\`polyfills`\`array.js:3:1`)
    at Module._compile (internal/modules/cjs/`loader.js:734:30`)
    at Object.Module._extensions..`js` (internal/modules/cjs/`loader.js:745:10`)
    at Module.load (internal/modules/cjs/`loader.js:626:32`)
    at tryModuleLoad (internal/modules/cjs/`loader.js:566:12`)
    at Function.Module._load (internal/modules/cjs/loader.js:558:3)`

知道如何解决这个错误吗？

我尝试了不同的方法，比如重新安装节点并升级到最新版本，但没有取得任何成功。

• 使用 npm init 创建节点项目 --yes
• npm install --save apollo-server graphql
• 从中复制 index.js https://www.apollographql.com/docs/apollo-server/getting-started.html
• 节点索引.js
