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.go package main import "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/go sudo tar -C /usr/local -xzf go1.14.1.darwin-amd64.tar.gz
