Gin always reports errors when loading index.html

r := gin.New()
r.Use(gin.Logger())
r.Use(gin.Recovery())
r.LoadHTMLGlob("views/**/*")
r.GET("/", func(g *gin.Context) {
    g.HTML(http.StatusOK, "index/index.html", gin.H{
        "title":"test",
    })

Can you please show a package structure? – Alex Pliutau

If your index.html file is located in views/index/index.html, you should use this wildcard. Also try to use ./.

r.LoadHTMLGlob("./views/*")
r.GET("/", func(g *gin.Context) {
  g.HTML(http.StatusOK, "index/index.html", gin.H{
    "title":"test",
  }
)

This problem dose not seem to be caused by template load,could you show your package info or show more code?

There is my package:

views
-|index
-|-|index.html
main.go

main.go: 

package main

import (
    "github.com/gin-gonic/gin"
    "net/http"
)

func main(){
    router := gin.Default()
    //define template dir
    router.LoadHTMLGlob("views/**/*")
    // handel router
    router.GET("/",func(c *gin.Context){
        c.HTML(http.StatusOK,"index/index.html",gin.H{
            "title":"test",
        })
    })

    router.Run(":8080")
}

views/index/index.html:

{{define "index/index.html"}}
    asdds
{{end}}

The demo can run normally.I found that only one difference is that if you use subdir in LoadHTMLGlob, I should define the template in html look like that：

{{define "index/index.html"}}{{end}}
