try to install Protobuf via:

pecl install Protobuf-3.1.0a1

[nevernet]

@langgo there are two ways to solve this issue:

first, use composer package:

{
    "name": "grpc/grpc-idcn",
    "description": "PHP",
    "require": {
        "google/protobuf": "v3.1.0-alpha-1",
        "grpc/grpc": "v1.0.0"
    }
}

add "google/protobuf": "v3.1.0-alpha-1", in composer.json file
and then composer install or composer updaate

second way:
use Protobuf php extension
