我正在尝试通过以下方式为我的Python代码创建gRPC绑定:
python -m grpc_tools.protoc -I $(pwd)/protos --python_out=./fino/pb2 --grpc_python_out=./fino/pb2 -I=$GOPATH/src -I=$GOPATH/src/github.com/gogo/protobuf/protobuf $(pwd)/protos/*
但是生成的文件有一个不存在的依赖项:
from github.com.gogo.protobuf.gogoproto import gogo_pb2 as github_dot_com_dot_gogo_dot_protobuf_dot_gogoproto_dot_gogo__pb2
这将在之后用于:
DESCRIPTOR = _descriptor.FileDescriptor(
name='oracle.proto',
package='oracle',
syntax='proto2',
serialized_pb=_b('\n\x0coracle.proto\x12\x06oracle\x1a-github.com/gogo/protobuf/gogoproto/gogo.proto\x1a\x1fgoogle/protobuf/timestamp.proto\x1a\x1bgoogle/protobuf/empty.proto\x1a\x0btypes.proto\":\n\x0b\x41\x63\x63ountList\x12+\n\x08\x61\x63\x63ounts\x18\x01 \x03(\x0b...')
,
dependencies=[github_dot_com_dot_gogo_dot_protobuf_dot_gogoproto_dot_gogo__pb2.DESCRIPTOR,google_dot_protobuf_dot_timestamp__pb2.DESCRIPTOR,google_dot_protobuf_dot_empty__pb2.DESCRIPTOR,types__pb2.DESCRIPTOR,])
显然,我不能运行这份代码。在尝试删除不存在的导入之后:
TypeError: Couldn't build proto file into descriptor pool!
Invalid proto descriptor for file "oracle.proto":
oracle.proto: Import "github.com/gogo/protobuf/gogoproto/gogo.proto" has not been loaded.
我尝试添加了
--include_imports --descriptor_set_out=$(pwd)/protos/all.proto
但我不确定如何将其添加到我的Python文件中。我只想在我的Python代码库中拥有自包含的描述。
编辑1: 示例proto文件:
syntax = "proto2";
package etcdserverpb;
import "github.com/gogo/protobuf/gogoproto/gogo.proto";
option (gogoproto.marshaler_all) = true;
option (gogoproto.sizer_all) = true;
option (gogoproto.unmarshaler_all) = true;
option (gogoproto.goproto_getters_all) = false;
message Request {

}
message Metadata {

}

-I<空格><参数>
和-I=<参数>
看起来很奇怪。而且,我不清楚-I=$GOPATH/src -I=$GOPATH/src/github.com/gogo/protobuf/protobuf
的目的是什么。这些是怎么出现在里面的?你想让它们做什么?你是根据哪个示例进行工作的?此外,你能分享一下你的.proto
