我正试图让一个iOS应用程序通过capacitorjs工作。
我已经通过Brew安装了最新的Ruby。
但现在似乎有一个问题，那就是cocopods一直试图使用旧的ruby（随操作系统安装和发货）。
建议更新ruby和可可pod ...但是现在“pod install”引用的是ruby 2.6而不是新的2.7版本。

pod --version

当我运行ruby on cli时，显示2个版本：

which -a ruby
/opt/homebrew/opt/ruby@2.7/bin/ruby
/usr/bin/ruby

当运行ruby版本时，比如说2.7：

ruby --version
ruby 2.7.7p221 (2022-11-24 revision 168ec2b1e5) [arm64-darwin22]

这是一个令人困惑的，但感觉像cocopods是配置在某处使用旧版本，而不是新版本？
有人能告诉我如何让pod使用安装的新版本吗？
我原以为安装ruby 2.7、导出path var并重新启动机器就可以解决链接问题，但没有什么用。
