将 macOS 从 12.x 升级到最新的 13.x 后，我的 React Native 0.70.1 的构建开始抛出上述错误。
ruby -vrbenv: version `2.7.5' is not installed (set by /Users/macair/documents/code/js/myapp/.ruby-version)
还有
brew -v
Homebrew 3.6.12
Homebrew/homebrew-core (git revision 1d7a7a30898; last commit 2022-11-22)
Homebrew/homebrew-cask (git revision c0c877a95b; last commit 2022-11-22)
但是，如果移出应用程序根目录或上面的其他目录，
ruby -vruby 3.1.2p20 (2022-04-12 revision 4491bb740a) [arm64-darwin21]
MacOS 13.x 正如其所说预装了 ruby 2.6.8，但在 Mac 上却找不到它。 react-native run-ios 和 pod install 都运行成功。然而构建确实失败了。

删除 pod file.lock 并运行 pod install 2 次后，构建错误消失。
您看到的错误消息表明未安装为您的项目指定的 Ruby 版本 (2.7.5)。您可以使用 rbenv 来管理 Ruby 版本并设置您的项目所需的版本。
DigitalOcean 有一篇很棒的文章，介绍了如何使用 rbenv 安装特定的 ruby 版本。
1.解决方案（最快）
2.解决方案
rbenv install 2.7.5
rbenv global 2.7.5
sudo gem install cocoapods
安装 2.7.5 并将其设置为全局后，请确保在安装 cocoapods 之前“ruby -v”打印出此版本。对我来说，我必须稍等一下，然后开始一个新的终端会话。
