Hi,

I am new to the bazel world, these is a problem when building brpc[1] with bazel.

The problem is that, bazel selects a non-compatible version of protobuf.

In the MODLES.bazel, required version of protobuf is 3.19.6.

```

bazel_dep(name = 'protobuf', version = '3.19.6', repo_name = 'com_google_protobuf')

```

When build, it selects 27.0.

> WARNING: For repository 'com_google_protobuf', the root module requires module version prot...@3.19.6, but got protobuf@27.0 in the resolved dependency graph.

How to find why bazel select this version of protobuf?

Thanks.

Thanks, this is really what I want.

BTW, problem solved by manually checking dependencies of all the
modules, email blocked by google :(
