I'm trying to create a grpc service in Python. I'm using Bazel to drive the
creation process.
My MODULE.bazel file:
module(name = "test", version = "1.0")
bazel_dep(name = "grpc", version = "1.63.1")
bazel_dep(name = "protobuf", version = "27.1")
My BUILD.bazel file:
package(default_visibility = ["//visibility:public"])
load("@grpc//bazel:python_rules.bzl", "py_grpc_library", "py_proto_library")
proto_library(
name = "service_proto",
srcs = ["service.proto"],
)
py_proto_library(
name = "service_py_proto",
deps = [":service_proto"],
)
py_grpc_library(
name = "service_py_grpc",
srcs = [":service_proto"],
deps = [":service_py_proto"],
)
The service itself is trivial:
syntax = "proto3";
package test;
service Service {
rpc Method(Request) returns (Response);
}
message Request {
optional string request = 1;
}
message Response {
optional string response = 1;
}
I first run `bazel clean --expunge` to make sure I'm in a clean state. Then
I do `bazel build //:service_py_grpc". After running a few thousand
actions, the build fails with:
ERROR:

Every undefined symbol starts with "Py". I'm assuming it's the Cython
implementation. What have I configured incorrectly?
