在安装RNPermissions及其依赖项时，我遇到了一个错误。似乎是我的编译器或正在安装的包有问题。
错误：

打开Xcode
1.选择Xcode后藤首选项...
1.选择位置并设置命令行工具

对我来说，运行
sudo xcode-select --reset修复了它。之前我还安装/更新了
gcc与brew upgrade gcc，不确定这是否是一个先决条件。7xllpg7q3#
通过XCode偏好设置设置您的XCODE CLI，然后再次运行pod安装。
Xcode -〉首选项-〉位置-〉命令行工具

有相同的问题，输出略有不同。通过接受Xcode许可证
sudo xcodebuild -license accept解决ymdaylpp5#
确保Xcode位于Applications文件夹中。
我不得不安装一个旧版本的Xcode，只是在~/下载中运行它。一旦我将Xcode.app文件移动（剪切/粘贴）到应用程序中，这个错误就消失了。

更新了GCC，问题就消失了。

我尝试了一系列的建议，并从这里找到了一个不理想的解决方案：https://github.com/facebook/react-native/issues/32291#issuecomment-929965479
我执行了
which gcc，并在上面引用的脚本中的export CC行上使用了该路径。当然，直接在
node_modules中编辑并不是最好的方法，因为它会被任何更新所破坏，但它至少允许pod install完成。
