go语言中一种常见的错误

本文是基于mac，安装go1.14版本之后，执行一个基本的go文件报错了。

错误现象：

执行下面的go的文件报下面的错误了

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

运行效果如下：

➜  test go run hello.go# runtime/internal/atomic/usr/local/go/src/runtime/internal/atomic/atomic_amd64x.go:13:6: Load redeclared in this block    previous declaration at /usr/local/go/src/runtime/internal/atomic/atomic_amd64.go:16:24/usr/local/go/src/runtime/internal/atomic/atomic_amd64x.go:19:6: Loadp redeclared in this block    previous declaration at /usr/local/go/src/runtime/internal/atomic/atomic_amd64.go:22:32/usr/local/go/src/runtime/internal/atomic/atomic_amd64x.go:25:6: Load64 redeclared in this block    previous declaration at /usr/local/go/src/runtime/internal/atomic/atomic_amd64.go:28:26/usr/local/go/src/runtime/internal/atomic/atomic_amd64x.go:31:6: LoadAcq redeclared in this block    previous declaration at /usr/local/go/src/runtime/internal/atomic/atomic_amd64.go:34:27/usr/local/go/src/runtime/internal/atomic/atomic_amd64x.go:36:6: Xadd redeclared in this block    previous declaration at /usr/local/go/src/runtime/internal/atomic/atomic_amd64.go:39:37/usr/local/go/src/runtime/internal/atomic/atomic_amd64x.go:39:6: Xadd64 redeclared in this block    previous declaration at /usr/local/go/src/runtime/internal/atomic/atomic_amd64.go:42:39/usr/local/go/src/runtime/internal/atomic/atomic_amd64x.go:42:6: Xadduintptr redeclared in this block    previous declaration at /usr/local/go/src/runtime/internal/atomic/atomic_amd64.go:45:47/usr/local/go/src/runtime/internal/atomic/atomic_amd64x.go:45:6: Xchg redeclared in this block    previous declaration at /usr/local/go/src/runtime/internal/atomic/atomic_amd64.go:48:36/usr/local/go/src/runtime/internal/atomic/atomic_amd64x.go:48:6: Xchg64 redeclared in this block    previous declaration at /usr/local/go/src/runtime/internal/atomic/atomic_amd64.go:51:38/usr/local/go/src/runtime/internal/atomic/atomic_amd64x.go:51:6: Xchguintptr redeclared in this block    previous declaration at /usr/local/go/src/runtime/internal/atomic/atomic_amd64.go:54:45/usr/local/go/src/runtime/internal/atomic/atomic_amd64x.go:51:6: too many errors

原因：

由于安装新版本的时候，没有删除旧版本，导致安装包的有些关联发生错误

解决方案：

先手动删除之前安装的包，再重新按照

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