我有 ios Cordova 项目，我想将 Firebase In-App Messaging 安装到我的项目中，我的 pod 文件如下所示：
platform :ios, '10.0'
target 'Feel Better' do
project 'Feel Better.xcodeproj'
pod 'Firebase/Core', '~> 4.1'
pod 'Firebase/DynamicLinks', '~> 4.1'
pod 'Fabric', '~> 1.7.11'
pod 'Crashlytics', '~> 3.10.7'
end
我按照 firebase 文档中的说明进行操作： https ://firebase.google.com/docs/in-app-messaging/get-started
我删除了 Firebase/Core 和 Firebase/DynamicLinks 库并添加了 Firebase，现在我的 pod 文件如下所示：
platform :ios, '10.0'
target 'Feel Better' do
project 'Feel Better.xcodeproj'
pod 'Fabric', '~> 1.7.11'
pod 'Crashlytics', '~> 3.10.7'
pod 'Firebase'
pod 'Firebase/InAppMessagingDisplay'
end
当我构建应用程序时，我收到了这个错误：
