把 pages 下面的單個js檔案，封裝上一個資料夾

var glob = require("glob");
const fs = require("fs-extra");
const l = console.log;

const dir = "./src/pages";

  if (er) return console.error(er);
  let fses = files.map(handleFile);
  for (let el of fses) {
    createDir(el.dirName).then(r => {
      if (r) {
        moveFile(el.oldSrc, el.newSrc);
      }
    });
  }
});

async function createDir(directory) {
  try {
    await fs.ensureDir(directory);
    return !0;
  } catch (err) {
    console.error(err);

  }
}

async function moveFile(oldSrc, newSrc) {
  try {
    await fs.move(oldSrc, newSrc);
    console.log(`success! ${oldSrc} to ${newSrc}`);
