我正在开发适用于 Android 和 iOS 的 Flutter 应用程序。该应用程序在 Android 模拟器上处于稳定的开发状态，因此我想尝试在 iOS 模拟器上运行它。 Macos 上的 Flutter 安装过程需要安装 Cocoapods。在尝试使用Macos安装Ruby并遇到权限错误后，我决定尝试asdf、最新版本的Ruby（Ruby 3.0.3p157（2021-11-24修订版3fb7d2cadc）[x86_64-darwin21]）和Cocoapods（1.11） .2).看起来安装成功，但是运行 pod 会出现以下错误：

我发布上述问题后，其他人也遇到了与此处报告的相同的问题：https://github.com/CocoaPods/CocoaPods/issues/11134
该问题的解决方法是使用 Ruby 2.7.5。安装该版本后，我发现 Cocoapods 1.11.2 与 Ruby 2.7.5 兼容。
