SyntaxError: Cannot use import statement outside a module. I'm using typescript and discord js

Question

我想弄清楚为什么我会遇到这个讨厌的错误： SyntaxError: Cannot use import statement outside a module 我正在使用 discord.js 和 typescript 创建一个 discord 机器人。我目前正在通过动态导入 commands 目录中的所有文件来创建自己的命令处理程序。但是，每当我导入此类文件时有问题的代码：

Promise.all((await getCommands("private")).map(async absPath => {
            return { name : basename(absPath), mod:  ( await import(absPath)).mod as fdjsMod  }
         })).then( modArr => {
             for ( const { name, mod } of modArr) {
                 publicMap.set(name.substring(0, name.length-3), mod)
             }
             
        })

import { Result, Err, Ok } from 'ts-results';

//^^^^^^^^^^ Cannot use import statement outside a module

import * as Handler from "../../types/index"

export default {
        alias: ["p"],
        type: Handler.CommandType.TEXT,
        delegate : () => {
            return Err("pong")
        }
} as Handler.fdjsMod

我的 tsconfig :

{
  "compilerOptions": {
    "resolveJsonModule": true,
    "outDir": "dist",
    "rootDir": "src"

  },
  "extends": "@tsconfig/node16/tsconfig.json"

我尝试过的事情：

在我的 package.json

这只会导致错误 exports is not defined in ES module scope

将 dist 文件夹 js 输出更改为 .cjs 文件

同样的错误

在 cjs require() 和动态 import() 之间切换 -同样的错误

我们将不胜感激。

尝试将这些属性添加到您的 tsconfig：

{
  "compilerOptions": {
    "resolveJsonModule": true,
    "outDir": "dist",
    "rootDir": "src",
    "module": "commonjs",
    "moduleResolution": "node",
    "esModuleInterop": true,
  },
  "extends": "@tsconfig/node16/tsconfig.json"
}

我不确定这是否适合你，但它适合我。

已解决：当我从我的命令文件夹动态导入文件时，我将它定向到我的 src 文件而不是 dist：

export default async function getCommands(type: privOrPub) : Promise<string[]> {
    //src/commands/public
    const publicCommands = join(process.cwd(), "src/commands/public")
    const privateCommands = join(process.cwd(), "src/commands/private")

    return type == 'private' ? readPath(privateCommands) : readPath(publicCommands)
}

export default async function getCommands(type: privOrPub) : Promise<string[]> {
    //src/commands/public -> dist/commands/public
    const publicCommands = join(process.cwd(), "dist/commands/public")
    const privateCommands = join(process.cwd(), "dist/commands/private")

    return type == 'private' ? readPath(privateCommands) : readPath(publicCommands)
}

谢谢大家的帮助。没想到错误这么小
