nodejs实现选择文件夹

const fs = require('fs');const path = require('path');let dir = process.argv[2] || '.';fs.readdir(dir, (err, files) => {  if (err) throw err;  console.log('请选择一个文件夹：');  files.forEach(file => {    let filePath = path.join(dir, file);    fs.stat(filePath, (err, stats) => {      if (err) throw err;      if (stats.isDirectory()) {        console.log(`[${file}]`);      } else {        console.log(file);      }    });  });  process.stdin.resume();  process.stdin.setEncoding('utf8');  process.stdin.on('data', data => {    data = data.trim();    let filePath = path.join(dir, data);    fs.stat(filePath, (err, stats) => {      if (err) throw err;      if (stats.isDirectory()) {        process.stdin.pause();        console.log(`已选择[${data}]文件夹！`);      } else {        console.log(`${data}不是一个有效的文件夹！`);      }    });  });});

const inquirer = require('inquirer');const fs = require('fs');const path = require('path');let dirs = fs  .readdirSync('.')  .filter(file => {    return fs.statSync(file).isDirectory();  })  .map(dir => {    return { name: `[${dir}]`, value: dir };  });inquirer  .prompt([    {      type: 'list',      name: 'dir',      message: '请选择一个文件夹：',      choices: dirs,    },  ])  .then(answer => {    console.log(`已选择[${answer.dir}]文件夹！`);  });

const fileTreeSelect = require('file-tree-select');const path = require('path');let dir = process.argv[2] || '.';let absDir = path.resolve(dir);fileTreeSelect(absDir, { hideFiles: true }).then(result => {  console.log(`已选择[${result}]文件夹！`);});
