xCode Cocoapods 构建失败 "Undefined symbols for architecture x86_64"

xCode Cocoapods build fails "Undefined symbols for architecture x86_64"

我想为模拟器和真实设备构建我的 Xcode 项目(react native & swift)。

模拟器运行良好。今天我尝试为我的设备构建它,我在 Xcode 栏中选择了我的设备并添加了要发布的方案(我必须这样做,因为我使用的是本机反应,否则捆绑包没有打包)

然后在构建过程中发生错误(在这种情况下是依赖 RNPurchases,但这完全是随机的。有时是 Expo-Keep-Awake 或 Facebook)

Undefined symbols for architecture x86_64:
"_OBJC_CLASS_$_RCPurchases", referenced from:
  objc-class-ref in RNPurchases.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

即使在我的方案中切换回构建配置 Debug 也不再有效。

我已经尝试了几件事:

没有任何效果。

这个问题对我来说很新,在过去的 2 个月内已经出现过两次。我以某种方式再次获得了模拟器 运行 的构建,但从未用于设备。半年前我没有这样的问题...

我的设置


    require_relative '../node_modules/react-native/scripts/react_native_pods'
    require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'
    require_relative '../node_modules/react-native-unimodules/cocoapods.rb' # expo uni modules

    use_frameworks!

    install! 'cocoapods', :deterministic_uuids => false, :warn_for_unused_master_specs_repo => false


    target 'TrainUrTeam' do
      platform :ios, '12.0'

      # ... pods xyz

      use_unimodules!

      config = use_native_modules!
      use_react_native!(:path => config["reactNativePath"])

    end


    post_install do |installer| # src: 
      installer.pods_project.targets.each do |target|
        target.build_configurations.each do |config|
          config.build_settings["ONLY_ACTIVE_ARCH"] = "YES"
        end
      end
    end

Go to xcode project -> Build setting -> Architecture -> Excluded architecture -> (arm64)set

尝试构建 & 运行

经过 2 周的谷歌搜索,我终于可以根据这个 Post 找到一个可行的解决方案,并将其添加到 Podfile:

use_frameworks! :linkage => :static

如果 use_frameworks! :linkage => :static 不适合您,您可以尝试使用:

pre_install do |installer|
 installer.pod_targets.each do |pod|
   if pod.name.eql?('RNPurchases')
     def pod.build_type;
     Pod::BuildType.static_library # pods version >= 1.9
     # Pod::Target::BuildType.static_library #  pods version < 1.9
    end
   end
 end
