降级grpc即可解决。

先装protobuf，在new工程不会出错了

强制绑定grpc 1.26.0

module kratos-demo

go 1.13

require (
	github.com/bilibili/kratos v0.3.4-0.20200306133340-7c946dc919c1
	github.com/gogo/protobuf v1.3.1
	github.com/golang/protobuf v1.3.5
	github.com/google/wire v0.4.0
	github.com/pkg/errors v0.9.1 // indirect
	google.golang.org/genproto v0.0.0-20200318110522-7735f76e9fa5
	google.golang.org/grpc v1.27.0
)

replace (
	github.com/coreos/go-systemd => github.com/coreos/go-systemd/v22 v22.0.0
	google.golang.org/grpc => google.golang.org/grpc v1.26.0
)

这个问题是 grpc 版本升级不兼容导致的，可以像 cjb21sj 所说的一样使用 v1.26.0，也可以参考以下链接替换成新的 API ：clientv3: Fix grpc-go(v1.27.0) incompatible changes to balancer/resolver. #11564
