Use the latest version. It works for "$1.0" in config.

使用1.8.3版本还是有问题

main.go

package main

import (
	"flag"
	"fmt"

	"github.com/zeromicro/go-zero/core/conf"
)

type Config struct {
	Price string
}

var configFile = flag.String("f", "config.yaml", "the config file")

func main() {
	flag.Parse()

	var c Config
	conf.MustLoad(*configFile, &c)
	fmt.Println(c.Price)
}

config.yaml

Price: '$1'

No problem here. You can check it.

conf.MustLoad(*configFile, &c, conf.UseEnv())

os.ExpandEnv() doesn't support escaping $ char. So if you want to use $ char, don't use conf.UseEnv().
