bazel 4.0.0 build failing

[viotemp1]

What is the problem?

bazel build -c fastbuild //:ray_pkg failing

Ray version and other system information (Python version, TensorFlow version, OS):
git origin/master

Reproduction (REQUIRED)

I followed the steps from https://docs.ray.io/en/master/development.html
Fast, Debug, and Optimized Builds

Error is
DEBUG: /home/.../git/ray/bazel/ray_deps_setup.bzl:63:14: No implicit mirrors used because urls were explicitly provided
ERROR: /home/.../.cache/bazel/bazel.../3d6f788daadb4d2ddf971c3424fdc02c/external/com_google_protobuf/BUILD:873:21: in proto_lang_toolchain rule @com_google_protobuf//:cc_toolchain: '@com_google_protobuf//:cc_toolchain' does not have mandatory provider 'ProtoInfo'.

bazel --version
bazel 4.0.0

• I have verified my script runs in a clean environment and reproduces the issue.
• I have verified the issue also occurs with the latest wheels.

made it finally following the diff from bazelbuild/bazel#12887
Maybe is not the right solution, there are come warnings when building...

I modified WORKSPACE like this.

I actually have some errors - from time to time. Not sure is this compilation is the problem. I found the same issue with ray-nightly also

[tisonkun]

It seems the same issue as #14117

[viotemp1]

True, I'll watch that Issue. This can be closed
