vision-camera-code-scanner 架构 x86_64 反应本机的未定义符号

问题描述 投票：0回答：3

在我的 React Native 项目中使用 

vision-camera-code-scanner
包时遇到构建错误。

速记错误是：

架构 x86_64 的未定义符号

完整错误如下：

我尝试通过运行以下类似的

问题
来解决问题：
pod deintegrate && pod cache clean --all
，然后在ios目录中运行pod install。

遗憾的是，这并没有解决问题，我还尝试了以下thread中建议的步骤：即排除目标arm64。但这也没有修复错误。

我还在这个 github thread 上阅读了以下内容：

这与 Google MLKit 团队不提供 ARM 模拟器二进制文件有关，我们无法自己编译，因为源代码不公开

所以现在我有点迷失了该怎么办。
非常感谢任何帮助或建议。

您必须按照以下步骤从 

pod 文件
中排除 arm64：

  1. 将其添加到您的 pod 文件中：
post_install do |installer|
  react_native_post_install(installer)
  installer.pods_project.build_configurations.each do |config|
    config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
  end
end
  1. 确保在您的 pod 文件中使用此 Flipper 版本：
use_flipper!({'Flipper' => '0.79.0'})
  1. 然后，清洁您的 Pod 并重新安装它们：
rm -rf ~/Library/Caches/CocoaPods && rm -rf ./ios/Pods && rm -rf ~/Library/Developer/Xcode/DerivedData/* && pod deintegrate && pod setup && npx pod-install
  1. 可选，iOS模拟器支持：

由于排除 

arm64
将阻止您的应用程序在本机模拟器上运行，因此您需要安装 Rosetta 支持并启用 Rosetta 模拟器：

$ software update --install-rosetta

如果没有这个，应用程序将启动，但一旦您尝试 MLKit 调用就会崩溃。

根据我对此主题的发现，Google MLKit 尚不支持 arm64（在尝试通过 iOS 项目上的 SPM 导入它的选项时发现它）。在 M1 机器上构建此程序的唯一方法是使用 Rosetta 2 在 x86_64 兼容性上运行整个项目。但是，Apple 不支持在兼容模式下运行 Xcode 配置，因此此选择可能会出现其他错误。

您必须通过ios模拟器使用rosetta。
