@googolgl ,hi ,
I used your code (fixed some syntax mistakes) to run on ubuntu 18.04.2 LTS multiple times, but no errors occurred.

The code that runs is as follows：

package main

import "github.com/xujiajun/nutsdb"


func initNutsdb() *nutsdb.DB {
	opt := nutsdb.DefaultOptions
	opt.Dir = "./nutsdb_data"
	opt.SegmentSize = 8388608
	opt.EntryIdxMode = nutsdb.HintKeyAndRAMIdxMode
	opt.SyncEnable = false
	opt.RWMode = nutsdb.FileIO
	opt.NodeNum = 1
	db, err := nutsdb.Open(opt)
	if err != nil {
		panic(err)
	}
	return db
}

func main() {
	initNutsdb()
}

BTW the latest version of nutsDB is 0.4.0 ，why github.com/xujiajun/nutsdb v0.4.1-xxx ?

I suggest you reinstall the nutsDB and try again.
