Xcode 12，框架构建失败，cocoapods，arm64

Question

我尝试使用cocoapods packager:从podspec生成一个框架

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

在Xcode 11中，一切都很好，但在Xcode 12中，我得到了以下错误：

致命错误：/应用程序/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/lipo：Pods/build/package.a和Pods/bbuild-sim/package.a具有相同的功能架构(arm64(，并且不能在同一个胖输出文件中

这里建议的解决方案：Xcode 12，为iOS模拟器构建，但在为iOS构建的对象文件中链接，用于添加架构arm64：

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

对我不起作用。这可能和我使用依赖关系的事实有关吗？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

sdk.public_header_files = [****]
end
end

更新：如果我添加--exclude-deps标志，它是有效的，但我的框架不包括依赖项。

通过修改本地cocoapods打包程序源ruby代码解决。修改的.rb文件的路径：

/Library/Ruby/Gems/2.6.0/Gems/coapods-packager-1.5.0/lib/cooapods-backager/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
