make generate: could not find protoc plugin for name openapiv2

[Lanskask]

What do I do and what is its result

$ make generate

# output
buf generate --path ./proto/helloworld/hello_world.proto
Failure: plugin openapiv2: could not find protoc plugin for name openapiv2
make: *** [generate] Error 1

I do it after

go get github.com/bufbuild/buf/cmd/buf 
go get github.com/grpc-ecosystem/grpc-gateway/v2/protoc-gen-grpc-gateway 
go get github.com/grpc-ecosystem/grpc-gateway/v2/protoc-gen-openapiv2 
go get google.golang.org/grpc/cmd/protoc-gen-go-grpc 
go get google.golang.org/protobuf/cmd/protoc-gen-go

What do I expect
