nodejs调用cmd命令实现复制目录

var dirCache = {};//缓存减少判断
function makedir (pathStr, callback) {
  if (dirCache[pathStr] == 1) {

        makedir(path.dirname(pathStr), function () {
          fs.mkdir(pathStr, function () {
            dirCache[pathStr] == 1;
            callback();
          })
        });
      }
    })
  }
