Question

此代码使用golang（1.8.3）的先前版本编译好，但在升级到新golang（1.9）后无法编译

~/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版本升级都会出现此错误，而不仅仅是我在这里提到的版本。

PS 发出时也会遇到相同的错误：go get -v -t ./...

解决方案：在安装新版本

之前，您必须先删除之前的golang安装

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

所以只需删除它

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

我使用的是Windows10。我必须使用控制面板卸载go18（当他要求卸载prev版本时，不要相信1.9安装程序 - 手动完成）。之后我删除了c：\ go - 默认的goroot，只有在此之后 - 安装1.9。就我而言，它是1.9.2 当然，检查你的GOROOT＆amp;＆amp; GOPATH

go build failed：runtime / mstkbar.go：151：10：debug.gcstackbarrieroff undefined
