mac x86_64，build lib25519失败

[Yinbenxin]

1.bazel build //... -c opt。 顺利完成编译

但是：
2.bazel run //yacl/crypto/ecc/lib25519:ed25519_test
(base) apple@ybx yacl % bazel run //yacl/crypto/ecc/lib25519:ed25519_test

bazel 6.5.0

@Yinbenxin 请使用 bazel 7.4.1 版本，或者使用 bazelisk

详情见：https://github.com/secretflow/yacl/blob/main/GETTING_STARTED.md#prerequisites

1.切换bazel版本
(base) apple@ybx yacl % bazel --version
ERROR: The project you're trying to build requires Bazel 6.5.0 (specified in /Users/apple/git/github/yacl/.bazelversion), but it wasn't found in /usr/local/Cellar/bazel/7.4.1/libexec/bin.

Bazel binaries for all official releases can be downloaded from here:
https://github.com/bazelbuild/bazel/releases

You can download the required version directly using this command:
(cd "/usr/local/Cellar/bazel/7.4.1/libexec/bin" && curl -fLO https://releases.bazel.build/6.5.0/release/bazel-6.5.0-darwin-x86_64 && chmod +x bazel-6.5.0-darwin-x86_64)
所以还是使用bazel 6.5.0

2.这个错误是lib25519的问题，和bazel版本关系不大吧？

yacl用的那个分支的？

//yacl/crypto/ecc/lib25519:ed25519_test 是跳过的，说明这个ed25519_test在我的机器上不能使用？

从代码中可以看到，需要系统=linux x86架构，mac os intel不兼容 可以尝试在docker 容器中尝试或更换测试设备
target_compatible_with = [
"@platforms//cpu:x86_64",
"@platforms//os:linux",
]
