Problem solving

1. Wrong or undefined files saving path:

ERROR:

WARNING: Malformed 'go_package' option in "proto/logger.proto", please specify:
option go_package = "./;__";

Solution option:

option go_package = "./pb";

2. Not found program (source):

ERROR:

protoc-gen-go-grpc: program not found or is not executable
Please specify a program using absolute path or make sure the program is available in your PATH system variable
--go-grpc_out: protoc-gen-go-grpc: Plugin failed with status code 1.

Solution option:

• Install the protocol compiler plugins for Go using the following commands:

go install google.golang.org/protobuf/cmd/protoc-gen-go@v1.26
go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@v1.1

• Update your PATH:

export PATH="$PATH:$(go env GOPATH)/bin"
