我的服务使用：
"start": "NODE_ENV=production node --optimize_for_size --trace-warnings --experimental-json-modules --es-module-specifier-resolution=node --no-warnings dist/server-new/server.js"

• • package. json**-注意它的类型是模块

{
    "name": "some-name",
    "license": "UNLICENSED",
    "version": "0.0.0",
    "description": "",
    "type": "module",
    "engines": {
        "node": "14.x",
        "npm": "6.14.x"
    },
...
}

• • 系统配置json**

{
    "extends": "../../tsconfig",
    "compilerOptions": {
        "noEmit": false,
        "rootDir": "."           /* Specify the root directory of input files. Use to control the output directory structure with --outDir. */,
        "outDir": "../../dist"  /* Redirect output structure to the directory. */
    },
    "module": "ESNext",
    "include": ["./*.ts", "package.json"],
    "resolveJsonModule": true
}

• • server. ts**-将api. js作为ES6模块导入

import cluster from 'cluster';
import os from 'os';
import App from './api.js';

...
    App.listen(port, () => {
        console.log(`express is listening on port ${port}`);
    });

• • api. ts**-能够导入express，但在导入GraphQL公共JS模块时遇到问题

import compression from 'compression';
import express from 'express';
import { graphqlHTTP } from 'express-graphql';
import { buildSchema } from 'graphql';
import CompanyController from './Controllers/CompanyController';

const App = express()
    .use(compression())
    ....
    );
export default App;

• • 在 * start * 脚本**期间出错：SyntaxError: The requested module 'graphql' is expected to be of type CommonJS, which does not support named exports. CommonJS modules can be imported by importing the default export.

参考import { buildSchema } from 'graphql';
所以我试了这个：

import * as graphQL from 'graphql';
const { buildSchema } = graphQL;

但随后我在这里得到TS错误...也许我现在需要解决这个问题，但不确定如何解决：
TypeError: buildSchema is not a function

• • 同时尝试：**

// eslint-disable-next-line @typescript-eslint/no-var-requires
const { buildSchema } = require('graphql');

• • 错误**：ReferenceError: require is not defined

因此，我不确定如何将这两项导入到api.ts中。
