问题：

github.com/coreos/etcd/clientv3/balancer/resolver/endpoint
../../pkg/mod/github.com/coreos/etcd@v3.3.18+incompatible/clientv3/balancer/resolver/endpoint/endpoint.go:114:78: undefined: resolver.BuildOption
../../pkg/mod/github.com/coreos/etcd@v3.3.18+incompatible/clientv3/balancer/resolver/endpoint/endpoint.go:182:31: undefined: resolver.ResolveNowOption
# github.com/coreos/etcd/clientv3/balancer/picker
../../pkg/mod/github.com/coreos/etcd@v3.3.18+incompatible/clientv3/balancer/picker/err.go:37:44: undefined: balancer.PickOptions
../../pkg/mod/github.com/coreos/etcd@v3.3.18+incompatible/clientv3/balancer/picker/roundrobin_balanced.go:55:54: undefined: balancer.PickOptions

方法：

//1)在你项目的go.mod中添加
replace google.golang.org/grpc => google.golang.org/grpc v1.26.0
//2)修改依赖为v1.26.0
go mod edit -require=google.golang.org/grpc@v1.26.0
//3)下载v1.26.0版本的grpc
go get -u -x google.golang.org/grpc@v1.26.0
