node.js - Nodejs FS |错误: ENOTDIR: not a directory

Question

所以我正在使用第三方项目，并且有以下代码块:

// walk through /run and remove all filecontents, keeping 1 level directories.
var root = '/run';

if (fs.existsSync(root)) {
  fs.readdirSync(root).forEach(cleanFileOrDir);
}

哪里cleanFileOrDir是:

function cleanFileOrDir(f) {
  var fPath = path.join(root, f);
  if (fs.statSync(fPath).isFile()) {
    // if its a file delete it right away
    rimraf.sync(fPath);
  } else {
    // remove its contents
    rimrafKidsSync(fPath);
  }
}

我收到以下错误:

fs.js:945
  return binding.readdir(pathModule._makeLong(path), options.encoding);
                 ^

Error: ENOTDIR: not a directory, scandir '/run/acpid.socket'

    at Module.load (module.js:458:32)
    at tryModuleLoad (module.js:417:12)

还有我的/run/的内容目录是:

acpid.socket   crond.pid          docker       irqbalance.pid  mlocate.daily.lock  pppconfig        snapd.socket  udev     wpa_supplicant
agetty.reload  crond.reboot       docker.pid   lightdm         mount               resolvconf       sudo          udisks2  xtables.lock
alsa           cups               docker.sock  lightdm.pid     network             rsyslogd.pid     systemd       user
avahi-daemon   dbus               initctl      lock            NetworkManager      sendsigs.omit.d  thermald      utmp
containerd     dhclient-wlo1.pid  initramfs    log             plymouth            shm              tmpfiles.d    uuidd

我认为这可能是 Nodejs v6 引入的问题文件系统可能已更改？

更新我修改了cleanFileOrDir函数看起来像这样:

function cleanFileOrDir(f) {
  var fPath = path.join(root, f);
  console.log(fPath);
  if (fs.statSync(fPath).isFile()) {
    // if its a file delete it right away
    console.log('Is file');
    rimraf.sync(fPath);
  } else {
    // remove its contents
    console.log('Is directory');
    rimrafKidsSync(fPath);
  }
}

我现在得到以下输出:

/run/NetworkManager
Is directory
/run/acpid.socket
Is directory
fs.js:945

简而言之，它正在处理 /run/acpid.socket作为一个目录，你知道为什么会这样吗？

由于“aspid.socket”是一个套接字，因此它不是常规文件，也不是目录。可用列表tests :

stats.isFile()
stats.isDirectory()
stats.isBlockDevice()
stats.isCharacterDevice()
stats.isFIFO()
stats.isSocket()

所以你需要改变逻辑:

function cleanFileOrDir(f) {
  var fPath = path.join(root, f);
  var stat = fs.statSync(fPath);

  if (stat.isFile()) {
    // if its a file delete it right away
    rimraf.sync(fPath);
  } else 
  if (stat.isDirectory()){
    // remove its contents
    rimrafKidsSync(fPath);
  } else
  if (stat.isSocket()) {
    // We do something with the socket
  }

}
