嵌入式Pods框架上的Xcode Swift CocoaPods pod spec lint失败

Question

我在尝试运行pod spec lint --verbose时遇到以下错误pod spec lint --verbose ：

Analyzed 1 podspec.

[!] The spec did not pass validation, due to 1 error and 5 warnings.

我知道我有一些警告我可以清理。 但是我得到的只有一个错误，那就是- ERROR | [OSX] xcodebuild: Returned an unsuccessful exit code. - ERROR | [OSX] xcodebuild: Returned an unsuccessful exit code. 。 Embed Pods Frameworks ，它说Embed Pods Frameworks是失败的原因。

不知道如何调试这个，因为我可以在Xcode中构建和运行示例项目。

下面我也附上了我的Podspec。

Pod::Spec.new do |s|
  s.name             = 'MySwiftPackage'
  s.version          = '0.1.0'
  s.summary          = 'A short description of MySwiftPackage.'

  s.description      = <<-DESC
TODO: Add long description of the pod here.
                       DESC

  s.homepage         = 'https://github.com/fishcharlie/MySwiftPackage'
  s.license          = { :type => 'MIT', :file => 'LICENSE' }
  s.author           = { 'fishcharlie' => 'fishcharlie.code@gmail.com' }
  s.source           = { :git => 'https://github.com/fishcharlie/MySwiftPackage.git', :tag => s.version.to_s }
  s.social_media_url = 'https://twitter.com/char_fish'

  s.ios.deployment_target = '9.0'
  s.osx.deployment_target = '10.11'
  s.swift_version = '4.2'

  s.source_files = 'MySwiftPackage/Classes/**/*', 'MySwiftPackage/ViewControllers/Shared/**/*'
  s.ios.source_files = 'MySwiftPackage/ViewControllers/iOS/**/*'
  s.osx.source_files = 'MySwiftPackage/ViewControllers/macOS/**/*'
  s.resources = 'MySwiftPackage/Assets/**/*.{ttf,xcassets}'

  s.dependency 'Alamofire', '4.7.3'
  s.dependency 'Bond', '6.10.2'
  s.ios.dependency '1PasswordExtension', '1.8.5'
end

关于如何修复/调试这个的任何想法？

Answer 1

尝试添加标志--no-clean 。 此标志使lint保留构建目录以供检查，因此您可以在工作区中调试构建失败，这可能更熟悉并为您提供更多信息。

看起来他们在pr github.com/CocoaPods/CocoaPods/pull/7720中修复了xcode 10，你可以尝试升级到1.6.0，或者将xcode降级到9.4。

Answer 2

错误应该是关于line 104: EXPANDED_CODE_SIGN_IDENTITY: unbound variable

解决方案（如github / Cocoapods上的问题7708所述 ）应该是将以下用户定义的设置添加到项目中：

EXPANDED_CODE_SIGN_IDENTITY="-"
EXPANDED_CODE_SIGN_IDENTITY_NAME="-"`
