Strange, the router is not registered #4008

Open RedCrazyGhost opened 4 months ago

RedCrazyGhost commented 4 months ago

Description

The gin code doesn't work, the router isn't registered and printed, and it doesn't panic

How to reproduce

package main

import (
    "net/http"

    "github.com/gin-gonic/gin"
)

func main(){
    r := gin.Default()

    r.GET("/", func(c *gin.Context) {
        c.String(http.StatusOK,"i'm ok!")
    })

    if err := r.Run(":8080");err != nil{
        panic(err)
    }
}

I tried using the new version of go and was able to start the service successfully

use go version go1.22.5 darwin/amd64 output:
