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(yùn)行
CORE_SECURITY_ENABLED=true ./vip
security.enabled: true
statetransfer.timeout.fullstate: 60s
peer.abcd: 3322d
