I'm finding that protoc doesn't seem to find things which are on the proto_path despite them being present:
$ protoc --proto_path=protobufs/protobufs \
--go_out=plugins=grpc:/home/me/go/src somefolder/enums.proto
somefolder/enums.proto: No such file or directory
$ ls protobufs/protobufs/somefolder/enums.proto
protobufs/protobufs/somefolder/enums.proto
Why might this happen? It doesn't seem to happen to others. I'm using Ubuntu 18.04, and protoc --version says libprotoc 3.0.0.
Can you try this command?
protoc --proto_path=protobufs/protobufs \
--go_out=plugins=grpc:/home/me/go/src \
protobufs/protobufs/somefolder/enums.proto
The proto_path argument is used to tell protoc where should it look for import proto files.
