First of all, the correct import is import "google/protobuf/empty.proto";

second, for generating a proto file run this code:

protoc --proto_path={proto_directory_address} --proto_path={proto_directory_name} --go-grpc_out={generated_directory_path} --go_out={generated_directory_path} {proto_directory_address}/{proto_file_name}.proto

hi there / i had the same issue for a long time .. this process worked for me i hope it dose for you too : navigate to this directory using your cmd(command line) :

cd .local/include

this directory normally should contain some folder named "google" copy this folder and paste it to this directory :

/usr/local/include

and now try the protoc engine again to generate your project and if the error still exists then try the rest of process :

navigate to that specific directory and check if its been copied or not . if it is then try to navigate to the folder from where you are (which it should be /usr/local/include) if the error says you have no permission to get in the folder use this command to get the permission

$ sudo chmod o+r -R ./google

and then try to get permission to get in protobuf folder in the same directory using above command again when its all done . check the protoc generator again /// hope works for you because it dose for me

I had the same problem because I had not installed the protoc correctly

For successful installation do these steps:

  1. Download latest version from here https://github.com/protocolbuffers/protobuf/releases
  2. Extract in your computer
  3. move bin/protoc to /usr/local/bin
sudo mv {downloaded_directory}/bin/protoc /usr/local/bin
  1. move include folder to /usr/local
sudo mv {downloaded_directory}/include /usr/local
