去構建失敗：運行/ mstkbar.go：151：10：debug.gcstackbarrieroff未定義

Question

該代碼使用golang（1.8.3）的以前版本編譯OK但是無法升級到新的golang（1.9）

之後編譯

~/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 

有什麼想法？實際上，這個錯誤發生在任何golang版本升級，而不僅僅是我在這裏提到的版本。

PS發行時，也得到同樣的錯誤：去拿-v -t/...

Answer 1

解決方案：必須先刪除以前golang安裝安裝新版本去之前

type go # issue this to confirm where your go lives 

的典型輸出：

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

所以只是將其刪除

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

安裝新版本

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

我使用Windows10之前。我必須使用控制面板卸載go18（當他要求卸載prev版本時，不要信任1.9安裝程序 - 手動執行）。之後，我刪除c：\ go - 默認goroot，並且只有在此之後 - 安裝1.9。在我的情況下，它是1.9.2 當然，檢查你的GOROOT & & GOPATH
