Installing Ruby 3.2.2 using rbenv on macOS M2: Missing psych and libyaml issues
问题
我在使用Mac上的M2 CPU上使用rbenv。我已经安装了Ruby 2.7.2，并希望安装Ruby 3.2.2。当运行"rbenv install 3.2.2"时，我遇到以下错误：
yaml.rb:3: warning: 似乎您的Ruby安装缺少psych（用于YAML输出）。
为了消除这个警告，请安装libyaml并重新安装Ruby。
Ruby的yaml扩展没有被编译。
错误：由于缺少扩展，Ruby安装中止
英文:
I am using rbenv on a Mac with an M2 CPU. I have ruby 2.7.2 installed and want to also install ruby 3.2.2. When running rbenv install 3.2.2, I get the following error:
yaml.rb:3: warning: It seems your ruby installation is missing psych (for YAML output).
To eliminate this warning, please install libyaml and reinstall your ruby.
The Ruby yaml extension was not compiled.
ERROR: Ruby install aborted due to missing extensions

我在Ubuntu 22.04上遇到了完全相同的问题。
修复方法是：
gem uninstall psych
gem uninstall openssl
然后再尝试。
英文:
I had the exact same problem in Ubuntu 22.04.
What fixed it for me was
gem uninstall psych
gem uninstall openssl
and trying again
