感谢您点击这个问题。我试图在没有外部库的情况下重新启动一个nodeJS进程。我做了这样的代码:

function restartProcess() {
spawn(process.argv[1], process.argv.slice(2), {
  detached: true, 
  stdio: ['ignore', out, err]
}).unref()
process.exit()
}
bot.on( "kicked", (reason) => {
    console.log("KICKED! "+ reason)
    restartProcess()
})

但是，当调用restartProcess()时，我会得到错误:

C:\Users\Toshiba\Desktop\program\mineflayer\spbot\bot.js:7
      stdio: ['ignore', out, err]
                        ^

ReferenceError: out is not defined
