英文:
go build fails : runtime/mstkbar.go:151:10: debug.gcstackbarrieroff undefined
问题
这段代码在之前的golang版本（1.8.3）中编译通过，但在升级到新的golang版本（1.9）后无法编译。
任何想法吗？实际上，这个错误发生在任何golang版本升级时，不仅仅是我在这里提到的版本。
PS 当执行go get -v -t ./...时也会出现相同的错误。
英文:

Any ideas ? Actually, this error happens for any golang version upgrade not just the versions I mentioned here.
PS Also get same errors when issuing : go get -v -t ./...

解决方案：在安装新的Go版本之前，您必须首先删除先前安装的Go。
输入以下命令以确认Go的位置：
type go
典型的输出为：
go is /usr/local/go/bin/go
删除/usr/local/go而不仅仅是/usr/local/go/bin/go，所以执行以下命令：
sudo rm -rf /usr/local/go
然后再安装新版本：
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 ${golang_ver}.linux-amd64.tar.gz
英文:
SOLUTION : you must first delete previous golang install prior to installing new go version
type go # issue this to confirm where your go lives
a typical output :
go is /usr/local/go/bin/go # delete /usr/local/go not just /usr/local/go/bin/go
so just remove it
sudo rm -rf /usr/local/go # OP's missing step else above errors
before you install new version
export golang_ver=$(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

我使用的是Windows10操作系统。我必须使用控制面板卸载go18（当1.9安装程序要求卸载之前的版本时，不要相信它，手动卸载）。之后，我删除了默认的goroot路径c:\go，然后才安装1.9版本。在我的情况下，安装的是1.9.2版本。当然，还要检查你的GOROOT和GOPATH设置。
英文:
I use Windows10. I have to uninstall go18 with Control Panel (do not trust 1.9 installer when he asks to uninstall prev version - do it by hands). After that I remove c:\go - the default goroot and only after this - install 1.9. In my case it was 1.9.2
And of course check your GOROOT && GOPATH
