然后在我的代碼中不起作用（打字稿節點）

Question

這是我的代碼：

var fs = require('fs');

var util = require('util');

var files = fs.readdirSync('*/path to my folder that contains subfolders*/')
async function getfilenum(){
  var files_v_num = []

for(const i in files){
  
files_v_num[i] = `${i} : ${files[i]}`

}
console.log('files_v_num',files_v_num);


const prompt = require('prompt');

prompt.start();

prompt.get([`number`], function (err, result) {
  if (err) {
    return onErr(err);
  }
  console.log('Command-line input received:');
  console.log('  Selected --------------->  ' +files_v_num[parseInt(result.number)] );
});

function onErr(err) {
  console.log(err);
  return 1;
}
}
async function Hello(){
  // await getfilenum()
  console.log('hello by meeeeeeeeeeeeeeeeeeeeeee')
}
getfilenum().then(Hello)

我想從用戶那里獲取號碼，然后打印'Hello by me'，但它只是像這樣打印：

[List of files]
prompt: number:  hello by meeeeeeeeeeeeeeeeeeeeeee

在得到我的輸入后，如何強制我的代碼由我打印你好？ 例如像這樣：

[List of files]
prompt: number: 3

你好，meeeeeeeeeeeeeeeeeeeeeee

由於prompt支持 Promise (async/await)，你最好堅持使用 Promise，而不是混合回調和 Promise：

const prompt = require('prompt');

async function getInput() {
    prompt.start();

    return prompt.get(['number']);
}

function showOutput(number) {
    console.log('Hello World!');
    console.log(number);
}

(async() => {
    const number = await getInput();
    showOutput();
})();
