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。

这是我在运行pod安装或pod更新后得到的消息:

[!] CocoaPods did not set the base configuration of your project because your project already has a custom config set. In order for CocoaPods integration to work at all, please either set the base configurations of the target `Runner` to `Target Support Files/Pods-Runner/Pods-Runner.debug-staging.xcconfig` or include the `Target Support Files/Pods-Runner/Pods-Runner.debug-staging.xcconfig` in your build configuration (`Flutter/Debug.xcconfig`).

[!] CocoaPods did not set the base configuration of your project because your project already has a custom config set. In order for CocoaPods integration to work at all, please either set the base configurations of the target `Runner` to `Target Support Files/Pods-Runner/Pods-Runner.release-staging.xcconfig` or include the `Target Support Files/Pods-Runner/Pods-Runner.release-staging.xcconfig` in your build configuration (`Flutter/Release.xcconfig`).

[!] CocoaPods did not set the base configuration of your project because your project already has a custom config set. In order for CocoaPods integration to work at all, please either set the base configurations of the target `Runner` to `Target Support Files/Pods-Runner/Pods-Runner.profile-staging.xcconfig` or include the `Target Support Files/Pods-Runner/Pods-Runner.profile-staging.xcconfig` in your build configuration (`Flutter/Release.xcconfig`).

下面是我解决这个问题的方法:

将方案添加到项目“Runner”下的Podfile

project 'Runner', {
  'Debug' => :debug,
  'Debug-staging' => :debug,
  'Profile' => :release,
  'Profile-staging' => :release,
  'Release' => :release,
  'Release-staging' => :release,
}

进入ios/颤振/调试。Xcconfig和include

#include "Pods/Target Support Files/Pods-Runner/Pods-Runner.debug-staging.xcconfig"

进入ios/Flutter/Release。Xcconfig和include

#include "Pods/Target Support Files/Pods-Runner/Pods-Runner.release-staging.xcconfig"
#include "Pods/Target Support Files/Pods-Runner/Pods-Runner.profile-staging.xcconfig"

颤振清洁 删除podfile.lock 酒吧得到 圆荚体安装

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。

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

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。

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。
