我正在尝试在我的 Rails(6) 应用程序中使用 ovirt-engine-sdk gem。在我的 mac ARM64 机器上捆绑安装失败。根据 gem 文档，gem 应该与 ruby 3.x 版本一起使用，但是当我进行捆绑安装时，我收到以下错误
gem install ovirt-engine-sdk
Building native extensions with: '--with-opt-dir=/opt/homebrew/opt/openssl@3 --with-ldflags=-L/opt/homebrew/opt/zstd/lib --with-cflags=-Wno-error=implicit-function-declaration'
This could take a while...

显然，Ruby 3 对这个 gem 的支持仍在进行中，请参阅以下拉取请求：https://github.com/oVirt/ovirt-engine-sdk-ruby/pull/10。事实上，如果您查看更改，C 扩展中存在一些更改，这些更改与
ruby_thread_has_gvl_p同时，您可以在 Gemfile 中指向该 GitHub 分支，这样您就可以测试修复：
gem "ovirt-engine-sdk", github: "jhernand/ovirt-engine-sdk-ruby", branch: "update_to_ruby_3"
