未定义Node.js path.resolve

// codenotworking

const path = require("path");
const fs = require("fs");
log = console.log;
const names = [];

function collectFileNamesRecursively(path) {
  fs.readdir(path, (err, files) => {
    err ? log(err) : log(files);

    // replacing paths
    for (const index in files) {
      const file = files[index];
      files[index] = path.resolve(path, file);
    }
    for (let file of files) {
      fs.stat(file, (err, stat) => {
        err ? log(err) : null;
        if (stat.isDirectory()) {
          collectFileNamesRecursively(file);
        }
        names.push(file);
      });
    }
  });
}
collectFileNamesRecursively(path.join(__dirname, "../public"));

我正在使用节点js v10.8.0,目录结构为

 - project/
 -     debug/
 -         codenotworking.js
 -     public/
 -        js/
 -            file2.js
 -        file.html

每当我运行此代码时,都会出现以下错误

TypeError:path.resolve不是函数     在fs.readdir(C:\ backup \ project \ debug \ codenotworking.js:17:24)     在FSReqWrap.oncomplete(fs.js:139:20)

我在这里做错了什么?
