goland开启服务器报错socket: operation not permitted

Question

linux系统;
当我运行

import (
    //_ "myproject/routers"
    "fmt"
    "net/http"
)

func IndexHandler(w http.ResponseWriter,req *http.Request){
    fmt.Fprintln(w, "hello world")
}

func main() {
    //beego.Run()
    http.HandleFunc("/hello",IndexHandler)
    err:=http.ListenAndServe("127.0.0.1:8080",nil)
    if err!=nil{
        panic(err)
    }
}

报错listen tcp :8080: socket: operation not permitted

Answer 1

看看是不是端口占用或者防火墙造成的。
