來自 CocoaPods 的錯誤 output：↳ 警告：CocoaPods 要求您的終端使用 UTF-8 編碼。 考慮將以下內容添加到 ~/.profile：

    export LANG=en_US.UTF-8
    

運行 pod install 時出錯 在 iPhone 12 Pro Max 上啟動應用程序時出錯。

Answer 1

只需將您的 cocoapos 版本更改為 1.10.2 即可解決您的問題。

首先卸載您當前的版本（無論它是什么）

就我而言，我從 1.11.1 版本降級

sudo gem uninstall cocoapods

然后只需安裝穩定版（截至 2021 年 11 月 11 日）

sudo gem install cocoapods:1.10.2

並再次構建您的應用程序。

如果仍然無法正常工作，請從構建目錄中刪除以下內容：

• 播客文件
• Podfile.lock
• Pods（目錄）和構建。

它為我修復了它，在過去幾天里兩次。

Answer 2

您可以通過在終端中輸入locale來檢查您的設置。 如果 LANG 為空字符串，則需要更改它。

這可以通過將行export LANG=en_US.UTF-8到您的 ~/.bashrc 或 ~/.zshrc 文件（取決於您使用的終端）來完成。

之后重新啟動您的終端，或鍵入source ~/.zshrc 。 通過檢查locale來仔細檢查更改是否到位。

之后，您可以再次嘗試flutter run以啟動您的 flutter 應用程序
