之后，我转到 iOS 子文件夹，希望pod install或pod install --repo-update帮助我解决问题，但是对于这两个实例中的任何一个，我都会在以下行之后继续收到所有这些错误行：

\n

 /Library/Ruby/Gems/2.6.0/gems/cocoapods-1.11.3/lib/cocoapods/user_interface/error_report.rb:34:in `force_encoding': can't modify frozen String\n(FrozenError)\n

\n

所有这些错误都是在我必须升级到蒙特雷之后开始的，以便使用 XCode 获得 SDK 13.0 及更高版本。

也尝试过flutter --doctor，但一切都井然有序。

需要注意的是，在这次升级之前，我确实制作了几个版本，甚至毫无问题地上传到 Apple Store。

Answer 1

它对我有用，在终端中执行此代码。

sudo gem update xcodeproj

Answer 2

我升级新版本的时候也出现了和你一样的错误，这是你的ios文件夹导致的错误

我通过以下方式修复了它：

删除项目中的 ios 文件夹

• 光盘
• rm -rf ios

复制旧的 ios 文件夹或生成新的 ios 文件夹

• 生成：flutter create -i swift

现在，您可以在 ios 文件夹中运行 pod install

• 吊舱设置
• 吊舱安装

祝你好运！
