grpc-gateway runtime version conflict

from last few days the protoc generator is generating code with v2 version of github.com/grpc-ecosystem/grpc-gateway. I want to keep using github.com/grpc-ecosystem/grpc-gateway v1.16.0. I am unable to remove the v2 version which is causing conflict. I tried removing from go.mod, clearing from $GOPATH. I suppose my protoc generator is not able to use v1 version. Kindly guide me as how shall I sync the grpc-gateway runtime package.

Using below commands to generate the messages and service

protoc -I . --go-grpc_out=. api/protobuf-spec/catalog_fetch/*.proto
protoc -I . --grpc-gateway_out=logtostderr=true:. api/protobuf-spec/catalog_fetch/*.proto

Note: It is generating both grpc.pb.go file and pb.go file, which is further causing issue.

cannot use mux (type *"github.com/grpc-ecosystem/grpc-gateway/runtime".ServeMux) as type *"github.com/grpc-ecosystem/grpc-gateway/v2/runtime".ServeMux ```

I have spent 3 hours debugging the exact same problem.

You have to remove the binary from your GOPATH and GOROOT.

For simplicity, just use which protoc-gen-grpc-gateway.

This should point you to the binary protoc is using under the hood. Remove it and rerun go get -u github.com/grpc-ecosystem/grpc-gateway/protoc-gen-grpc-gateway@v1.16.0.
