Bazel 8 build: "unknown repo 'io_bazel_rules_closure'"

[Geremia]

I'm trying to build tensorboard master, but I get this error:

$ bazel build tensorboard
Starting local Bazel server (8.1.0) and connecting to it...
WARNING: --enable_bzlmod is set, but no MODULE.bazel file was found at the workspace root. Bazel will create an empty MODULE.bazel file. Please consider migrating your external dependencies from WORKSPACE to MODULE.bazel. For more details, please refer to https://github.com/bazelbuild/bazel/issues/18958.

It refers me to https://bazel.build/external/migration.

Perhaps BUILD needs updating for Bazel 8?

[arcra]

We haven't migrated to use Bazel modules, and Bazel 8 doesn't support the previous model anymore.

You can use bazelisk to use a previous version of bazel, and this should unblock you to build the product.
