error: 修改config/local.yml的MySQL 数据库连接, 然后使用 nunu run ,报错, 只有使用 go run ./cmd/server -conf=config/prod.yml 才能正确启动

[formal-you]

我在使用 [nunu-layout-advanced]模板后,修改了 conf/local.yml, conf/prod.yml 的 MySQL 数据库连接, 并修改了 internal/repository/repository.go:30

	db, err := gorm.Open(mysql.Open(conf.GetString("data.mysql.nunu")), &gorm.Config{})// 使用我自己创建数据库

随后使用 nunu run 命令启动 报错:

 D:/LeetCode/Golang/Go-Web/github.com/formal-you/nunu-hello/internal/repository/repository.go:30
[error] failed to initialize database, got error dial tcp 127.0.0.1:3306: connectex: No connection could be made because the 
target machine actively refused it.
panic: dial tcp 127.0.0.1:3306: connectex: No connection could be made because the target machine actively refused it.

        D:/LeetCode/Golang/Go-Web/github.com/formal-you/nunu-hello/cmd/server/main.go:16 +0x5c
exit status 2

但当我改为使用 go run ./cmd/server -conf=config/prod.yml

D:\LeetCode\Golang\Go-Web\github.com\formal-you\nunu-hello>go run ./cmd/server -conf=config/prod.yml
load conf file: config/prod.yml
{"level":"info","ts":1693402524.6552145,"caller":"server/main.go:20","msg":"server start","host":"http://172.27.32.1:8000"}  

能够正常启动, conf/local.yml, conf/prod.yml 我都同步修改了MySQL 数据库连接. 按说 使用 go run ./cmd/server -conf=config/local.yml 不会报错, 但同样会报上面的错误.

如果想指定nunu run时的配置文件路径，当前不支持通过命令行的方式指定。

我们暂时可以用过环境变量指定配置文件：

linux or macos

APP_CONF=./config/prod.yml nunu run

windows（注意两个命令需分开执行）

$env:APP_CONF="./config/prod.yml"

nunu run

[formal-you]

我说的是: nunu run 默认加载 ./config/local.yml, 但我的 conf/local.yml, conf/prod.yml 我都同步修改了MySQL 数据库连接, 我想知道到, nunu run , go run ./cmd/server -conf=config/local.yml 这两个为什么都会报错.
