编译失败 (goroutine 导致)

初学go，尝试用robotgo包捕捉键盘输入，一直编译不通过，可能是对goroutine理解有问题，还请前辈指点迷津.

package main

import (
    "fmt"
    "github.com/go-vgo/robotgo"
)

type word struct {
    key  string
    desc string
}

func keybord(action chan string, words []word, quit chan int) {
    for _, v := range words {
        go func(w word) {
            // fmt.Println("go func param")
            // fmt.Println(word)
            if event := robotgo.AddEvent(w.key); event == true {
                // fmt.Println("event")
                // fmt.Println(w.key)
                if (w.desc == "bye") {
                    quit <- 0
                }

                action <- w.desc
            }
        }(v)
    }
}

func main() {
    action := make(chan string)
    quit := make(chan int)

    fmt.Println("监控键盘输入")

    if event := robotgo.AddEvent("down"); event == true {
        fmt.Println("down")
    }

    words := []word{
        {"right", "向右"},
        {"left", "向左"},
        {"up", "向上"},
        {"down", "向下"},
        {"esc", "bye"},
    }

    keybord(action, words, quit)

    for {
        select {
        case tmp := <-action:
            fmt.Println("main")
            fmt.Println(tmp)
        case <-quit:
            fmt.Println("main")
            fmt.Println("quit")
            return
        }
    }
}

关键报错信息：

...
SIGABRT: abort
PC=0x7fffcb415dda m=4 sigcode=0

goroutine 0 [idle]:

谢谢.
