Ios C编译器无法创建可执行文件（安装CoCoapod）

在安装RNPermissions及其依赖项时，我遇到了一个错误。我的编译器或正在安装的程序包似乎有问题

错误：

更新了GCC，问题消失了

brew update
brew upgrade
brew info gcc
brew install gcc
brew cleanup

---

对于我来说，运行

sudoxcode选择--reset

修复了它

---

在此之前，我还使用

brew upgrade gcc

安装/更新了

gcc

，不确定这是否是一个先决条件。

也有相同的问题，输出略有不同。通过接受Xcode许可证解决

sudo Xcode构建-许可证接受

打开Xcode

选择Xcode转到首选项…

选择位置并设置命令行工具

---

通过XCODE首选项设置XCODE CLI，然后再次运行pod安装

---

Xcode->Preferences->Locations->命令行工具

我认为GCC与此无关。xcode重置应该可以解决这个问题。xcode默认使用GCC还是单独的编译器？嗨，Peter G，你有什么解决方案来解决这个问题？
