此代码使用golang的先前版本（1.8.3）进行了编译，但是升级到新的golang（1.9）后无法编译

有任何想法吗 ？实际上，任何golang版本升级都会发生此错误，而不仅仅是我在这里提到的版本。
PS 发行时也会遇到相同的错误：go -v -t。/ …
解决方案：您必须先删除以前的golang安装，然后再安装新的go版本
type go # issue this to confirm where your go lives
典型输出：
go is /usr/local/go/bin/go # delete /usr/local/go not just /usr/local/go/bin/go
所以就删除它
sudo rm -rf /usr/local/go # OP's missing step else above errors
在安装新版本之前
export golang_ver=$(curl https://golang.org/VERSION?m=text 2> /dev/null) wget https://storage.googleapis.com/golang/${golang_ver}.linux-amd64.tar.gz sudo tar -C /usr/local -xzf ${golang_ver}.linux-amd64.tar.gz
