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
别瞎捣鼓了，重置。
循序渐进的
显示项目导航器 选择项目 选择信息 在Configurations中，选择每个目标，一次一个(Debug, ApplicationUnitTest, Release，等等)，对于每个目标，将configuration设置为None。 确保“基于配置文件”为每个配置读取0配置集或无配置集。这是关键所在。 Xcode辞职 rm -rf Pods/ Podfile。锁;圆荚体安装
一旦你允许pod安装在第7步中发挥它的魔力，你就可以使用自定义配置并更改配置。
其他回答
我在安装吊舱时也犯了同样的错误。我尝试了所有方法(重新安装pod，更新所有宝石等)，并找到了适合我的解决方法。因为改变目标的名字，所以出现了问题。在这种情况下，解决方案很简单:
单击“产品->方案->管理方案…” 单击列表上的目标，并在窗口底部用“-”符号删除它。 点击“+”将目标添加回列表。选择正确的目标和名称。
毕竟，一切都应该正常工作。
我错了:
diff: /../Podfile.lock: No such file or directory diff: /Manifest.lock: No such file or directory error: The sandbox is not in sync with the Podfile.lock.
我只是检查了我安装吊舱的路径，并纠正了它，重新安装，它只是工作。
确保在.xcodeproj或.xcworkspace(如果已经存在的话)存在的位置前面给出路径。
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.
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。
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
