无法生成代码Go：“在此块中重新声明”

当我尝试构建go build hello.go时，请执行以下代码：

// ~/go/src/myproj/hello.go
package main

import "fmt"

func main() {
    fmt.Printf("hello, world\n")
}

我收到以下错误：

我的Go设置： Go版本：go1.14.4Linux/amd64 GOPATH:/home/jiren/go GOROOT:/usr/local/go 路径：PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin:/usr/local/go/bin

你知道有什么问题吗

我希望有人能向我解释如何解决这个问题。

我知道GOPATH和GOROOT的含义，因此无需参考其他解决方案\文档

@Burak Serdar建议重新安装Go解决了这个问题。 出现问题是因为我在上一版本的基础上安装了Go的新版本

解决方案： 1. : rm-rvf/usr/local/go/ 2.请从以下位置重新安装：
