最近剛拿到公司的 Mac Book Pro M3，

想用 Capacitor 編譯 iOS app 時，

出現了 Skipping pod install because CocoaPods is not installed 的錯誤訊息：

雖然好像只是個警告訊息，但接下來的編譯就都沒有成功…

照著網路上的文章，想用 gem 來安裝 CocoaPods，

(gem 是 Ruby 的套件管理員，CocoaPods 是 Swift/Objective-C 的套件管理員)

印象中在舊的 Mac Book Pro (Intel) 沒有問題，

但在 Apple M3 上就卡住了… 我只能按 Ctrl-C 來中斷：

$ sudo gem install cocoapods

^CERROR:  Interrupted

加上  

它陷在無窮迴圈，感覺像是有檔案不存在，但我也不知道原因…

$ gem install --debug cocoapods

亂爬文的時候，看到有人是用 Homebrew 來安裝 CocoaPods 的，

一試就成功了，有看到它是去抓 arm64 用的套件：

brew install cocoapods

再度用 Capacitor 來編譯，這次就成功囉～
