[goctl-env]: preparing to check env

[goctl-env]: looking up "protoc"
[goctl-env]: "protoc" is installed

[goctl-env]: looking up "protoc-gen-go"
[goctl-env]: "protoc-gen-go" is installed

[goctl-env]: looking up "protoc-gen-go-grpc"
[goctl-env]: "protoc-gen-go-grpc" is installed

[goctl-env]: congratulations! your goctl environment is ready!
