Xcode12，框架构建失败，cocoapods，arm64

Question

从 podspec 生成一个框架

pod package MyCore.podspec --embedded --subspecs=SDK

在 Xcode 11 中，一切正常，但在 Xcode 12 中，出现以下错误：

fatal error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/lipo: Pods/build/package.a and Pods/build-sim/package.a have the same architectures (arm64) and can't be in the same fat output file

这里建议的解决方案：补充：

s.pod_target_xcconfig = { 'EXCLUDED_ARCHS[sdk=iphonesimulator*]' => 'arm64' }
s.user_target_xcconfig = { 'EXCLUDED_ARCHS[sdk=iphonesimulator*]' => 'arm64' }

对我不起作用。这与我使用依赖项的事实有关吗？有人知道如何解决这个问题吗？

Podspec: 
#
# Be sure to run `pod lib lint **.podspec' to ensure this is a
# valid spec and remove all comments before submitting the spec.
#
# Any lines starting with a # are optional, but encouraged
#
# To learn more about a Podspec see http://guides.cocoapods.org/syntax/podspec.html

      sdk.public_header_files = [****]
    end

end

更新：如果我添加 --exclude-deps 标志，它可以工作，但我的框架不包含依赖项。

通过修改本地cocoapods-packager源ruby代码解决。修改后的 .rb 文件路径：

/Library/Ruby/Gems/2.6.0/gems/cocoapods-packager-1.5.0/lib/cocoapods-packager/pod_utils.rb (path may be different /Users/USER/.rvm/gems/ruby-2.6.3/gems/cocoapods-packager-1.5.0/lib/cocoapods-packager/pod_utils.rb)

unless static_installer.nil?
  static_installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['CLANG_MODULES_AUTOLINK'] = 'NO'
      config.build_settings['GCC_GENERATE_DEBUGGING_SYMBOLS'] = 'NO'
      config.build_settings['EXCLUDED_ARCHS[sdk=iphonesimulator*]'] = 'arm64' // <-- inserted here
    end
  end
  static_installer.pods_project.save
end
