然后在我的代码中不起作用（打字稿节点）

Question

这是我的代码：

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)

我想从用户那里获取号码然后打印 'Hello by me' 但它只是像这样打印：

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

如何强制我的代码在收到我的输入后准确地由我打印 hello？例如像这样：

[List of files]
prompt: number: 3

你好，来自 meeeeeeeeeeeeeeeeeeeeeeeee

由于 prompt 支持 promises (async/await)，您最好坚持使用 promises 而不是混合回调和 promises:

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();
})();
