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

进入XCode，打开你的项目设置，在信息选项卡下，你会看到“配置”，在这里你可以设置调试和发布的配置文件。显然，您已经将这些设置为一些自定义配置，CocoaPods希望/需要您使用Pods配置。

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。

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`).

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

播客文件中产生问题的行是:link_with ['BluePlaquesLondon'， 'BluePlaquesLondonFramework']。

只是让这个:link_with ['BluePlaquesLondon']或这个(在我的情况下工作，希望它会在你的:-)):

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'

xcodeproj 'BluePlaquesLondon.xcodeproj'
inhibit_all_warnings!
link_with ['BluePlaquesLondon']

def import_pods

     pod 'TTTAttributedLabel', '~> 1.10.1'
     pod 'GoogleAnalytics-iOS-SDK', '~> 3.0.9'
     pod 'Google-Maps-iOS-SDK'
     pod 'IntentKit'
     pod 'HCViews'
     pod 'SVProgressHUD', :head
     pod 'iRate'
     pod 'iOS-KML-Framework', :git => 'https://github.com/FLCLjp/iOS-KML-Framework.git'

end

import_pods

target "BluePlaquesLondonFramework" do
    import_pods
    pod 'Kiwi'
end

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。
