What did you do?

package enums

import (
	"database/sql/driver"

	"github.com/gogf/gf/v2/util/gconv"
)

//go:generate stringer -type DictValueType -linecomment -output dict_string.go
type DictValueType int

func (t DictValueType) Value() (driver.Value, error) {
	return int64(t), nil
}

func (t *DictValueType) Scan(src interface{}) error {
	if value, ok := src.(int64); ok {
		*t = DictValueType(value)
		return nil
	}
	if value, ok := src.([]uint8); ok {
		*t = DictValueType(gconv.Int64(string(value)))
		return nil
	}
	return nil
}

const (
	StringDictValueType   DictValueType = iota // String

)

What did you see happen?

When I was using Go version 1.23, this could be generated normally. However, after I upgraded to version 1.24, it no longer generates correctly and throws an error.

stringer: internal error: package "database/sql/driver" without types was imported from "web-server/internal/enums"
enums.go:9: running "stringer": exit status 1

What did you expect to see?

The expectation is for the code to be generated normally.

I have resolved the issue; after deleting the stringer binary file and reinstalling it, everything works fine now. Thank you.
