go語言中的常見錯誤和解決方法

本文是基于mac，安裝go1.14版本之后，執(zhí)行一個基本的go文件報錯了。

錯誤現(xiàn)象：

執(zhí)行下面的go的文件報下面的錯誤了

# hello.go
package main

import "fmt"

func main(){
    fmt.Println("hello world")
}

運行效果如下：

?  test go run hello.go
# runtime/internal/atomic

原因：

由于安裝新版本的時候，沒有刪除舊版本，導(dǎo)致安裝包的有些關(guān)聯(lián)發(fā)生錯誤

解決方案：

先手動刪除之前安裝的包，再重新按照

rm -rf /usr/local/go
sudo tar -C /usr/local -xzf go1.14.1.darwin-amd64.tar.gz
