Question

我第一次尝试打字稿和纱线，并在尝试运行 yarn node . 时遇到以下错误：

yarn node v1.22.10
file:///Users/stevenbarber/devl/MLBStatsSDK/lib/query.js:1
const axios = require('axios').default;
              ^

ReferenceError: require is not defined

error Command failed.
Exit code: 1

Output:

ts.config 看起来像

{
    "compilerOptions": {
        "target": "es2020"
    },
    "module": "esnext"
}

package.json 看起来像

{
  "dependencies": {
    "@types/node": "^14.14.25",
    "axios": "^0.21.1",
    "dotenv": "^8.2.0",
    "typescript": "^4.1.3",
    "typings": "^2.1.1"
  },
  "type": "module",
  "private": true
}

index.ts 看起来像

require('dotenv').config()

import Players from './lib/player/players.js'

const players = new Players()
console.log(players.search('sosa', true))

并在我运行 tsc

时编译成这个

require('dotenv').config();
import Players from './lib/player/players.js';
const players = new Players();
console.log(players.search('sosa', true));

我发现的大多数建议往往涉及 require 不适用于客户端，并且只能在 node 中使用，但由于我在 node 中运行它，我不确定这如何适用。

另外值得注意的是，当我从 "type": "module" 中删除 package.json 时，正如一些人在其他线程中所建议的那样，我得到了这个：

SyntaxError: Cannot use import statement outside a module

Output:

运行“纱线节点”时出现“ReferenceError: require is not defined”。
