React Native iOS - 架构x86_64未定义符号

Question

我已经开发了一款React Native应用程序，在Android上运行良好......但是当我尝试在iOS上构建时，出现以下错误：Undefined symbols for architecture x86_64 看起来这与Flipper有关，因为详细的错误如下所示：

我在m1上也遇到了同样的问题，做了以下操作后解决了：

修改构建设置 -> 排除架构选项，添加任何iOS模拟器SDK选项，并将值设置为arm64。如图所示：

然后在Podfile中添加以下代码：

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['EXCLUDED_ARCHS[sdk=iphonesimulator*]'] = "arm64"
    end
  end
end

谢谢! 更改Podfile就解决了问题-不需要进行Xcode更改部分。 - MasterPiece

我不明白这个问题 - 我使用的是M1芯片的Mac，所以我的模拟器在运行arm64架构，对吗？为什么要排除该架构呢？顺便问一下，为什么还要构建任何基于x86_64的内容呢？ - iameli

创建静态库时，将为实际设备（arm64）和模拟器（x86_64）分别打包版本。在英特尔 Mac 上，模拟器使用 x86_64 指令没有问题，但在 M1 Mac 上会出现问题。在排除 arm64 架构后，模拟器仍然以 arm64 模式运行，但模拟器中的应用程序以 x86 模式运行。https://juejin.cn/post/7037037120158269448 - Z Hu
