Flutter 词法或预处理器问题 (Xcode)：找不到“GoogleMobileAds/GoogleMobileAds.h”文件

Question

将 flutter 更新到最新版本后，我不断收到 GoogleMobileAds 和 GoogleMaps

的错误

当我尝试

flutter build ios

时，我遇到了同样的错误

Lexical or Preprocessor Issue (Xcode): 'GoogleMaps/GoogleMaps.h' file not found /Users/.../.pub-cache/hosted/pub.dev/google_maps_flutter_ios-2.3.1/ios/Classes/GoogleMa pPolylineController.h:5:8

Lexical or Preprocessor Issue (Xcode): 'GoogleMobileAds/GoogleMobileAds.h' file not found /Users/.../.pub-cache/hosted/pub.dev/google_mobile_ads-4.0.0/ios/Clas ses/NativeTemplates/GoogleAdsMobileIosNativeTemplates/GADTTemplateView.h:14: 8

（取决于在 pubspec 中找到哪个包）

系统

• macOS：13.5.1
• x代码：15.2
• Flutter 版本 3.19.1
• Dart 版本 3.3.0
• CocoaPods 版本 1.15.1

在我第一次遇到这个问题的项目中，有很多包，但一开始我使用的是 google_mobile_ads：^2.3.0

许多人建议尝试一个新项目，但没有运气，我遇到了同样的问题，我也尝试了谷歌广告存储库中的示例之一，我也遇到了同样的问题...... 我什至尝试从 Codemagic 构建我的应用程序，但我再次遇到同样的问题......

我也尝试过：

• 使用 2 个软件包的较低版本

• rm -rf Pods Podfile.lock

• pod cache clean --all

  以及

  flutter pub cache clean

• 在 Podfile 中添加 2 个包
• 分解 Pod 并安装/更新

我已经寻找解决方案两个多星期了，现在这变得非常令人沮丧，请帮助我解决这个问题。下面是我的 podfile 和 pubspec 的依赖项。

Podfile

# Uncomment this line to define a global platform for your project
platform :ios, '14.0'

# CocoaPods analytics sends network stats synchronously affecting flutter build latency.
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
  pod 'MLKitVision', :podspec => 'MLKitVision.podspec.json'
  pod 'MLKitCommon', :podspec => 'MLKitCommon.podspec.json'

  use_frameworks!
  use_modular_headers!

  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
end

post_install do |installer|
  # Ensure pods also use the minimum deployment target set above
  # https://stackoverflow.com/a/64385584/436422
  puts 'Determining pod project minimum deployment target'

  pods_project = installer.pods_project
  deployment_target_key = 'IPHONEOS_DEPLOYMENT_TARGET'
  deployment_targets = pods_project.build_configurations.map{ |config| config.build_settings[deployment_target_key] }
  minimum_deployment_target = deployment_targets.min_by{ |version| Gem::Version.new(version) }

  puts 'Minimal deployment target is ' + minimum_deployment_target
  puts 'Setting each pod deployment target to ' + minimum_deployment_target

  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
    target.build_configurations.each do |config|
      #config.build_settings['ENABLE_BITCODE'] = 'NO'
      config.build_settings[deployment_target_key] = minimum_deployment_target
    end
  end
end

发帖希望有一天这可以帮助别人。我最终从我的 MacBook 中完全删除了 pub 缓存和可可豆荚，然后重新安装它们。完成后，我的应用程序再次正常工作。
