【问题描述】：

此代码使用先前版本的 golang (1.8.3) 编译正常，但升级到新的 golang (1.9) 后编译失败

~/src/gopath/src/github.com/scottstensland/infosynth $ go build infosynth.go
# runtime
/usr/local/go/src/runtime/mstkbar.go:151:10: debug.gcstackbarrieroff undefined (type struct { allocfreetrace int32; cgocheck int32; efence int32; gccheckmark int32; gcpacertrace int32; gcshrinkstackoff int32; gcrescanstacks int32; gcstoptheworld int32; gctrace int32; invalidptr int32; sbrk int32; scavenge int32; scheddetail int32; schedtrace int32 } has no field or method gcstackbarrieroff)

/usr/local/go/src/runtime/mstkbar.go:248:41: undefined: stkbar
/usr/local/go/src/runtime/mstkbar.go:227:19: too many errors

有什么想法吗？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 发出时也会出现同样的错误：go get -v -t ./...

标签： go installation

【解决方案1】：

解决方案：在安装新的 go 版本之前，您必须先删除以前的 golang 安装

type go    # issue this to confirm where your go lives

一个典型的输出：

go is /usr/local/go/bin/go  # delete /usr/local/go not just /usr/local/go/bin/go

所以删除它

sudo rm -rf /usr/local/go  #  OP's missing step else above errors

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

【解决方案2】：

我使用的是 Windows10。我必须使用控制面板卸载 go18（当他要求卸载以前的版本时不要相信 1.9 安装程序 - 手动执行）。之后我删除 c:\go - 默认的 goroot 并且仅在此之后 - 安装 1.9。就我而言，它是 1.9.2 当然还要检查你的 GOROOT && GOPATH
