當目標目錄已用于較舊的Go安裝并且某些文件已被重命名（與以前的版本相比）時，此錯誤是可重現的并且會發生。
例如：
Go 1.13.8中的文件go/src/runtime/internal/atomic/atomic_amd64x.go已移至Go 1.14go/src/runtime/internal/atomic/atomic_amd64.go中。
在不清理目標目錄的情況下提取會觸發“先前聲明”錯誤，因為func Xchguintptr在go/src/runtime/internal/atomic/atomic_amd64x.go和go/src/runtime/internal/atomic/atomic_amd64.go
為避免此類錯誤，請刪除安裝文件夾 ( /usr/local/go ) 并重新安裝Go 1.14。
sudo rm -rf /usr/local/go && sudo tar -C /usr/local -xzf go1.14.linux-amd64.tar.gz
再次測試：
~/go/src/hello go version
go version go1.14 linux/amd64
~/go/src/hello go build hello && go run hello
hello, world
