无法使用 gRPC 构建 go_proto_library

Question

我开始使用 bazel 并尝试为 golang 生成 RPC 服务的 protobuf 代码。

当我尝试构建它时出现以下错误：

bazel-out/k8-fastbuild/bin/examples/grpc/protos/helloworld_go_proto_/examples/grpc/protos/helloworld.pb.go:229:7: undefined: grpc.ClientConnInterface
bazel-out/k8-fastbuild/bin/examples/grpc/protos/helloworld_go_proto_/examples/grpc/protos/helloworld.pb.go:233:11: undefined: grpc.SupportPackageIsVersion6
bazel-out/k8-fastbuild/bin/examples/grpc/protos/helloworld_go_proto_/examples/grpc/protos/helloworld.pb.go:243:5: undefined: grpc.ClientConnInterface
bazel-out/k8-fastbuild/bin/examples/grpc/protos/helloworld_go_proto_/examples/grpc/protos/helloworld.pb.go:246:26: undefined: grpc.ClientConnInterface

代码如下：https://github.com/juanique/example-go-grpc。我正在尝试包含尽可能少的代码以使该目标正常工作。

由于 BUILD 文件是由 gazelle 生成的，我怀疑问题出在 WORKSPACE 文件中：https://raw.githubusercontent.com/juanique/example-go-grpc/main/WORKSPACE. I'm just doing what I found in https://github.com/bazelbuild/rules_go

更新：看起来肯定是版本问题：https://github.com/grpc/grpc-go#compiling-error-undefined-grpcsupportpackageisversion

不是 bazel 用户，但经过几个小时的测试，我发现你的 rpc 版本应该更高：

 go_repository(
     name = "org_golang_google_grpc",
-    build_file_proto_mode = "disable",
     importpath = "google.golang.org/grpc",
-    sum = "h1:J0UbZOIrCAl+fpTOf8YLs4dJo8L/owV4LYVtAXQoPkw=",
-    version = "v1.22.0",
+    sum = "h1:f+PlOh7QV4iIJkPrx5NQ7qaNGFQ3OTse67yaDHfju4E=",
+    version = "v1.41.0",
 )

然后你就可以构建它了：

 ~/code/example-go-grpc (main*) [09:45:55]
p1gd0g$ bazel build //examples/grpc/protos:helloworld_go_proto
INFO: Analyzed target //examples/grpc/protos:helloworld_go_proto (49 packages loaded, 306 targets configured).

并且我建议使用 gazelle 和 go.mod 来生成 WORKSPACE。演示：https://github.com/p1gd0g/helloworld
