ios - 在将 Firebase 云消息传递依赖项添加到 PubSpec.yaml -Flutter 时构建应用程序失败

Question

当我使用 VScode 或终端或 XCode 构建应用程序时，它在不添加依赖项的情况下运行完美，但是当我将依赖项添加到我的 Pubspec.yaml 时，我收到以下错误:

---

/ios/Pods/GoogleDataTransport/GoogleDataTransport/GDTCCTLibrary/GDTCCTUploadOperation.m:36:9: fatal error: 'GoogleUtilities/GULURLSessionDataResponse.h' file not found
    #import <GoogleUtilities/GULURLSessionDataResponse.h>
            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    1 error generated.

    note: Planning build
    note: Constructing build description
Could not build the application for the simulator.
Error launching application on iPhone 11.
Exited (sigterm)**

**

我尝试在此处搜索解决方案，但找不到任何解决方案。 我尝试过的以前的解决方案是:

1. 先运行 Flutter Clean，然后运行 ​​Flutter Run(无效)
2. 删除 Podfile.lock 和 podfile 以及 .xcworkspace 文件，然后在终端中运行 pod install(没有用)
3. 广告连播更新

这是我的 flutter 医生 Trace:

这是我的 PodFile:

    ENV['COCOAPODS_DISABLE_STATS'] = 'true'
    
    project 'Runner', {
      'Debug' => :debug,
      'Profile' => :release,
      'Release' => :release,
    }
    
    def flutter_root
      generated_xcode_build_settings_path = File.expand_path(File.join('..', 'Flutter', 'Generated.xcconfig'), __FILE__)
      unless File.exist?(generated_xcode_build_settings_path)
        raise "#{generated_xcode_build_settings_path} must exist. If you're running pod install manually, make sure flutter pub get is executed first"
      end
    
      File.foreach(generated_xcode_build_settings_path) do |line|
        matches = line.match(/FLUTTER_ROOT\=(.*)/)
        return matches[1].strip if matches
      end
      raise "FLUTTER_ROOT not found in #{generated_xcode_build_settings_path}. Try deleting Generated.xcconfig, then run flutter pub get"
    end
    
    require File.expand_path(File.join('packages', 'flutter_tools', 'bin', 'podhelper'), flutter_root)
    
    flutter_ios_podfile_setup
    
    target 'Runner' do
      use_frameworks!
      use_modular_headers!
    
      flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
    end
    
    post_install do |installer|
      installer.pods_project.targets.each do |target|
        flutter_additional_ios_build_settings(target)
      end
    end

这是我的 pubspec.yaml，是的，我使用的是旧版本的 firebase 云消息传递，这是由于 firebase Core 和新的 Firebase 云消息传递版本“^9.0.0”之间的依赖冲突

 version: 1.0.0+1
    
    environment:
      sdk: ">=2.7.0 <3.0.0"

我终于想出了解决办法。解决方案是在 firebase 中创建 iOS App 时不遵循 firebase.google.com 上的指南。您应该严格遵守 https://firebase.flutter.dev/docs/overview/ 上的指南

回顾一下我采取的步骤:

1. 创建了一个新的 flutter 项目
2. 在 pubspec.yaml 中添加了 firebase_core: "0.7.0"under dependencies。酒吧得到了吗
3. 浏览到项目目录 > iOS 文件夹 > 打开 projectname.xcworkspace
4. 点击 Runner 并在 General 中复制 Bundle Identifier。
5. 在“常规”选项卡的“开发信息”中将 iOS 版本更改为 10 或更高版本
6. 将这个 Bundle Identifier 粘贴到“Add Firebase to your iOS app” Step 1 Register
7. 点击下一步并下载 GoogleService-Info.plist
8. 在 projectname.xcworkspace 中点击顶部的 Runner。右键单击并按“将文件添加到 Runner”。浏览 GoogleService-Info.plist 文件。确保启用“需要时复制项目”复选框
9. 完成后运行该项目，无需采取任何进一步的步骤，它应该可以正常工作。

我刚刚创建了两个新项目以确保它在发布到这里之前可以正常工作并且工作正常。我希望它也对你有用。
