編譯

go get github.com/spf13/viper
go build -o vip

處理go get github.com/spf13/viper過程中問題

unrecognized import path "golang.org/x/sys/unix"
unrecognized import path "golang.org/x/text/transform"
unrecognized import path "golang.org/x/text/unicode/norm"
解決辦法：
git clone https://github.com/golang/sys.git $GOPATH/src/golang.org/x/sys
git clone https://github.com/golang/text.git $GOPATH/src/golang.org/x/text

運行

CORE_SECURITY_ENABLED=true ./vipsecurity.enabled: truestatetransfer.timeout.fullstate: 60speer.abcd: 3322d
