在通道上迭代时出现错误“范围内变量太多”

我在这里有点迷路了,我试图让一个goroutine添加到一个数组中,并从中读取另一个goroutine,我怀疑它与下面的内容有些接近,但我需要使用wait()来处理。

但是,我得到了错误 prog.go:19:14: too many variables in range ,第19行是 for _, v := range c { 我在网上找不到答案,我在这里做什么或不做什么?

package main

import (
    "fmt"
    //"time"
    "sync"
)

func hello(wg *sync.WaitGroup, s []int, c chan int) {
    for _, v := range s {
        c <- v
    }
    fmt.Println("Finished adding to channel")
    wg.Done()
}

func hello2(wg *sync.WaitGroup, c chan int) {
    fmt.Println("Channel",c)
    for _, v := range c {
        fmt.Println("Received",v)   
    }
    fmt.Println("Finished taking from channel")
    wg.Done()
}

func main() {
    s := []int{1, 2, 3, 4, 5}
    var c = make(chan int, 5)


    var wg sync.WaitGroup
    wg.Add(1)
    go hello(&wg, s, c)
    wg.Wait()
    wg.Add(1)
    go hello2(&wg, c)
    wg.Wait()
    //time.Sleep(1 * time.Second)
    fmt.Println("main function")
}
