在我的项目的基础上执行pod安装后，我得到以下错误:
CocoaPods没有设置项目的基本配置，因为您的项目已经有一个自定义配置集。为了实现CocoaPods集成，请将目标BluePlaquesLondonFramework的基本配置设置为Pods/ target Support Files/Pods/Pods.debug.xcconfig，或者在构建配置中包含Pods/ target Support Files/Pods/Pods.debug.xcconfig。
这可能听起来像是一个愚蠢的问题，但是我如何为目标设置基本配置呢?
https://github.com/seanoshea/BluePlaquesLondon/blob/ios8/Podfile是导致此问题的Podfile。
如果你想知道这个项目是什么样子的话，iOS 8分支上的http://github.com/seanoshea/BluePlaquesLondon就是这个问题中的Podfile。
当前回答
你还应该确保在Podfile的根目录中没有pod，你应该像这样定义在许多目标中使用的所有pod:
def shared_pods
pod 'ReactiveCocoa', '~> 2.5'
end
target 'app' do
shared_pods
pod 'RestKit'
end
target 'tests' do
shared_pods
pod 'OCMock'
end
您还可能需要删除libPods。libPods-app. a和libPods-app。A从目标依赖项，执行一个清洁，然后运行pod安装再次。
其他回答
所以对我来说，这个问题是由于前面提到的xcconfig文件名在Swift 3更新发生之前被更改了。
有些东西是不同步的，所以Cocoapods创建了一个“恢复引用”文件夹部分与旧的命名文件，并链接到它们。
为了解决这个问题，我:
删除了“恢复的引用”文件夹和包含旧的 Xcode和文件系统中的.xcconfig文件 Xcode辞职 运行pod安装
从那以后，一切都为我处理好了，警告也消失了。
我也遇到了同样的问题，但是在Xcode 6.1.1中-为我修复它的是将两个pod相关目标的配置文件设置更改为None，然后再次运行pod install。
通过选择项目(而不是目标)，然后选择Info选项卡，可以找到配置文件设置。
Sorry my previous answer was unclear. This was just one of many errors i've got while trying to set up Cloud Firestore, so this answer is specific for that situation. In order to solve this error and make firebase work, eventually, you have to follow all of the steps from this page: https://firebase.flutter.dev/docs/firestore/overview/ . If you are having problems with generating the 'firebase_options.dart' file, then you need to follow the steps on this page: https://firebase.google.com/docs/cli#mac-linux-auto-script . The last step is optional, but it reduces build time, and I really don't know how or why, but it made some of other errors also disappear... Step 4. Improve iOS & macOS build times, from this page https://firebase.flutter.dev/docs/firestore/overview/. And off course, don't forget to add dependencies in pubspec.yaml: https://pub.dev/packages/firebase_core/install . There is also a great comment here about using Firebase.initializeApp() : https://stackoverflow.com/a/63492262/17626190
如果您正在使用自定义配置，您可以按照警告中的建议，将Pod配置包含在配置文件中
#include "Pods/Target Support Files/Pods-YYY/Pods-YYYY.develop-archive.xcconfig"
这将不会停止警告，但将允许您使用您的私人配置(在CocoaPods项目的警告上有一个开放的错误) https://github.com/CocoaPods/CocoaPods/issues/2633
Add the relevent xcconfig files to your project. Cocoapods will have created them but you can't set them in Xcode until they are in the project. You probably want to add them to the Pods group where the other pods xcconfig files are. Right click and add files. Search for xcconfig files in your project folder or look in Pods/Target Support Files/[TARGET_NAME]/ (I have different cocoapods configured for each target (extension and main project this may be slightly different in your case) Go to project configurations in the Info of your main project For each target and configuration set the appropriate pods configuration. pod install again and you should see no errors.
