Xcode Swift CocoaPods pod spec lint 在 Embed Pods 框架上失败

Question

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

sent 1312397 bytes  received 106 bytes  2625006.00 bytes/sec

Analyzed 1 podspec.

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

我知道我有一些可以清理的警告。但我得到的只有一个错误，即- ERROR | [OSX] xcodebuild: Returned an unsuccessful exit code.。除此之外，它还说Embed Pods Frameworks 是失败的原因。

不确定如何调试它，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/调试此问题的任何想法？

Answer 1

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

解决方案（如Issue 7708 on github/Cocoapods 中所述）应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="-"`

Answer 2

尝试添加标志--no-clean。此标志使 lint 离开构建目录 完好无损以供检查 因此您可以在可能更熟悉的工作区中调试构建失败并为您提供更多信息。

看起来他们在 github.com/CocoaPods/CocoaPods/pull/7720 中为 xcode 10 修复了此问题，您可以尝试升级到 1.6.0，或将 xcode 降级到 9.4。
