go - 当我试图访问 Go 中的常量时，为什么会出现堆栈溢出？
问题描述
我目前正在使用“Go 编程语言”作为我的指南来学习 Go。我试图让一个简单的包导入工作，但它总是导致堆栈溢出。我有一个简单的包，tempconv用于处理温度转换。它位于$GOPATH/src/goPractice/tempconv。该main软件包位于$GOPATH/src/goPractice/cf. 包tempconv由两个文件组成，“tempconv.go”和“conv.go”。
// tempconv.go
// Package tempconv performs Celsius and Fahrenheit conversions.
package tempconv
import "fmt"
type Celsius float64
type Fahrenheit float64
const (
AbsoluteZeroC Celsius = -273.15
FreezingC Celsius = 0
BoilingC Celsius = 100
)
func (c Celsius) String() string { return fmt.Sprintf("&g°C", c) }
func (f Fahrenheit) String() string { return fmt.Sprintf("%g°F", f) }
// conv.go
package tempconv
// CtoF converts a Celsius temperature to Fahrenheit.
func CToF(c Celsius) Fahrenheit { return Fahrenheit(c*9/5 + 32) }
func FToC(f Fahrenheit) Celsius { return Celsius((f - 32) * 5/9) }
最后，位于 中的“main.go”cf如下：
// main.go
// Cf converts its numeric argument to Celsius and Fahrenheit.
package main
import (
"fmt"
// "os"
// "strconv"
"goPractice/tempconv"
)
func main() {
fmt.Print(tempconv.AbsoluteZeroC)
}
它应该做的远不止这些，但现在我只是在测试它是否可以打印一些像常量一样简单的东西。当我运行由 生成的二进制文件时go build main.go，出现错误。它遵循：
