运行pod安装时出错在iPhone X上启动应用程序时出错。

Answer 1

我的设置：VS Code、Flutter

如果您没有 Podfile.lock 文件并且 pod update 没有帮助，请尝试以下操作：

转到项目中的 ios/Pods/Local Podspevs 目录
检查每个 json 文件以找到所需的最高 ios 版本。其中一些是我的"ios": "10.0"
返回到 ios/ 目录
打开 Podfile 个文件
取消注释 # platform :ios, '9.0' 并将 9.0 替换为 2. step 中的版本，例如 10.0。
- # platform :ios, '9.0' > platform :ios, '10.0'
运行pod install，错误应该消失了

Answer 2

pod update

应该做到这一点。不客气：-）

Answer 3

当您升级FlutterFire软件包并尝试针对iOS或macOS进行构建时，可能会发生此问题，通常是以下情况之一：

您的iOS或macOS目录中的Podfile.lock版本已过期，并且已锁定到Firebase iOS SDK的较早版本，而新升级的FlutterFire软件包可能正在使用这些SDK的较新版本。

解决方案：删除Podfile.lock文件，然后再次尝试构建。此文件将在下一个pod install之后重新生成。

您的Pod规格存储库已过时，这意味着CocoaPods在本地不了解最近发布的Firebase iOS SDK的任何潜在的较新版本。

解决方案：在终端中运行pod repo update，然后再次尝试构建。

Answer 4

仅在 pod 文件上取消注释

# platform :ios, '9.0'

并取悦它 platform :ios, '10.0'

然后删除 Podfile.lock 并重新安装您的应用

Answer 5

我有一个类似的问题。将Project，Target和Podfile设置为iOS 12并失败。

这是我的Podfile：

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '12.0'
use_frameworks!

abstract_target 'all_pods' do
    pod 'Alamofire'
    pod 'AlamofireImage'
    pod 'AlamofireNetworkActivityIndicator'
    pod 'Atributika'
    pod 'AXPhotoViewer'
    pod 'Cache'
    pod 'Crashlytics'
    pod 'Fabric'
    pod 'Firebase/Core'
    pod 'Firebase/Messaging'
    pod 'Google-Mobile-Ads-SDK'
    pod 'GTMNSStringHTMLAdditions'
    pod 'KVLoading'
    pod 'MGSwipeTableCell'
    pod 'ReachabilitySwift'
    pod 'SDCAlertView'
    pod 'SideMenuSwift'
    pod 'SwiftyJSON'
    pod 'SwiftyUserDefaults'
    pod 'UIImageViewAlignedSwift'

target 'Test Poject' do
#    all_pods
end

end

先确定要崩解

pod解体

运行强制回购更新

pod安装--repo-update

Answer 6

我花了将近一个月的时间来解决这些问题。我已经尝试了这篇文章中的所有建议以及我在网上找到的许多其他建议，但没有任何效果。这个问题的真正解决方案是什么？下面是我仍然收到的错误消息，flutter 代码在 Android 上编译得很好，但在 iOS 上一次又一次地失败了。我需要它同时适用于两个平台。我已经构建、未构建、清理、移除、解体、失效、清理缓存、更新存储库、rm -rf'd 一百次，在 Android Studio 中创建了一个全新的项目，但没有任何效果。 Flutter 医生报告一切正常。

我什至从来没有得到要删除的 pubspec.lock 文件，因此任何尝试的建议都不存在。

你说得对，我试过了。

下面的各种输出 - 如果您看到某些内容，请说些什么。我真的可以在这里使用一些急需的帮助 - 将不胜感激！

这是当前在我的 pubspec.yaml 中的内容 - 正如您所看到的，我一直在尝试各种软件包版本的组合来让 pub 安装成功完成 - 这种组合有效 - 其他较新的组合也可以下拉但在尝试为 iOS 编译和运行时，它们最终会失败。

Answer 7

Cocoapods拒绝更新到最新的Firebase，因为依赖项需要更高的最低部署目标。

解决方案：更新您的部署目标

Answer 8

我遇到了同样的问题，但这对我有帮助。

pod 'Firebase/Core', '>= 0'
pod 'FirebaseCrashlytics', '>= 0'

它会将 FirebaseCore 和 FirebaseCrashlytics 更新到最新版本

Answer 9

我在使用 firebase Admob 时遇到了类似的问题，我的问题是我同时使用了 admob_flutter 和 firebase_admob 软件包。一旦我从 pubspec.yaml 中删除了 admob_flutter 包，一切正常！

CocoaPods找不到Pod“ Firebase / Core”的兼容版本| cloud_firestore，Flutter
