sql包的“导入错误数据库/ sql”

Question

sql包的“导入错误数据库/ sql”。 我想在控制器上使用connect方法。 我认为需要安装sql程序包。

controllers/gorm.go

import (
 "database/sql"
_ "github.com/go-sql-driver/mysql"
"github.com/jinzhu/gorm"
"github.com/revel/revel"
"myapp/app/models"
"log"
)

添加数据库/ sql，然后尝试导入。 但是发生了错误。

错误

Revel engine is NOT listening on.. localhost:58929
