iOS 上的 Firebase 设置 (Flutter)

问题描述 投票：0回答：4

我尝试按照原始指南在 Flutter 中的 iOS 上设置 Firebase，但在终端中输入 

pod install
后收到以下消息：

[!] CocoaPods could not find compatible versions for pod "Firebase/Auth":
  In snapshot (Podfile.lock):
    Firebase/Auth (= 6.34.0, ~> 6.0)

  In Podfile:
    firebase_auth (from `.symlinks/plugins/firebase_auth/ios`) was resolved to 1.4.1, which depends on
      Firebase/Auth (= 8.0.0)


You have either:
 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
 * changed the constraints of dependency `Firebase/Auth` inside your development pod `firebase_auth`.
   You should run `pod update Firebase/Auth` to apply changes you've made.

我在 main.dart 文件中所做的所有更改是将默认的 main 函数更改为：

    Future main() async {
      WidgetsFlutterBinding.ensureInitialized();
      await Firebase.initializeApp();
      runApp(MyApp());
    }

我的 pubspec.yaml 文件的相关部分如下所示：


    firebase_storage: ^8.0.3
    cloud_firestore: ^1.0.5
    firebase_auth: ^1.1.0

我根据使用空安全的视频选择这些数字，但也尝试了几个不同的数字，例如此处提到的数字： https://firebase.google.com/docs/flutter/setup#analytics-enabled，也是最新的，但错误是一样的。

我尝试重新安装 cocoapods 并进行了 pod repo update、pod setup、pod install 多次，但输出是相同的。在Podfile中，我取消了ios版本号的注释，并将其更改为10，正如许多来源推荐的那样。 我非常感谢您在这方面的帮助。

编辑： 这是我原来的 Podfile：

    # Uncomment this line to define a global platform for your project
    platform :ios, '10.0'
    
    # 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
      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

解决方案： 我将 Podfile 更改为：


    platform :ios, '12.0'
    
    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
    
    def flutter_install_ios_plugin_pods(ios_application_path = nil)
      ios_application_path ||= File.dirname(defined_in_file.realpath) if self.respond_to?(:defined_in_file)
      raise 'Could not find iOS application path' unless ios_application_path
    
      symlink_dir = File.expand_path('.symlinks', ios_application_path)
      system('rm', '-rf', symlink_dir) # Avoid the complication of dependencies like FileUtils.
    
      symlink_plugins_dir = File.expand_path('plugins', symlink_dir)
      system('mkdir', '-p', symlink_plugins_dir)
    
      plugins_file = File.join(ios_application_path, '..', '.flutter-plugins-dependencies')
      plugin_pods = flutter_parse_plugins_file(plugins_file)
      plugin_pods.each do |plugin_hash|
        plugin_name = plugin_hash['name']
        plugin_path = plugin_hash['path']
        if (plugin_name && plugin_path)
          symlink = File.join(symlink_plugins_dir, plugin_name)
          File.symlink(plugin_path, symlink)
    
          if plugin_name == 'flutter_ffmpeg'
              pod 'flutter_ffmpeg/full-lts', :path => File.join('.symlinks', 'plugins', plugin_name, 'ios')
          else
              pod plugin_name, :path => File.join('.symlinks', 'plugins', plugin_name, 'ios')
          end
        end
      end
    end
    
    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)
        target.build_configurations.each do |config|
            config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '10.0'
        end
      end
    end

我遇到了同样的问题，只需将 Podfile 中的目标更改为 

platform :ios, '14.0'
即可解决它

然后在您的项目中 

cd ios
到您的 iOS 文件夹 - 运行：

  1. rm -rf Pods/ Podfile.lock

  2. pod repo update

  3. pod install

对于 M1 Mac 用户 - 运行此命令：

  1. rm -rf Pods/ Podfile.lock

  2. sudo arch -x86_64 gem install ffi

  3. arch -x86_64 pod repo update

  4. pod install

错误应该消失了

但是您可能会遇到最后一个错误：

[!] 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.profile.xcconfig` or include the `Target Support Files/Pods-Runner/Pods-Runner.profile.xcconfig` in your build configuration (`Flutter/Release.xcconfig`).

按照 StackOverFlow 答案所示在 Xcode 中设置配置来解决它

这是我当前的 Podfile 设置，你可能想尝试一下：

platform :ios, '12.0'

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

def flutter_install_ios_plugin_pods(ios_application_path = nil)
  ios_application_path ||= File.dirname(defined_in_file.realpath) if self.respond_to?(:defined_in_file)
  raise 'Could not find iOS application path' unless ios_application_path

  symlink_dir = File.expand_path('.symlinks', ios_application_path)
  system('rm', '-rf', symlink_dir) # Avoid the complication of dependencies like FileUtils.

  symlink_plugins_dir = File.expand_path('plugins', symlink_dir)
  system('mkdir', '-p', symlink_plugins_dir)

  plugins_file = File.join(ios_application_path, '..', '.flutter-plugins-dependencies')
  plugin_pods = flutter_parse_plugins_file(plugins_file)
  plugin_pods.each do |plugin_hash|
    plugin_name = plugin_hash['name']
    plugin_path = plugin_hash['path']
    if (plugin_name && plugin_path)
      symlink = File.join(symlink_plugins_dir, plugin_name)
      File.symlink(plugin_path, symlink)

      if plugin_name == 'flutter_ffmpeg'
          pod 'flutter_ffmpeg/full-lts', :path => File.join('.symlinks', 'plugins', plugin_name, 'ios')
      else
          pod plugin_name, :path => File.join('.symlinks', 'plugins', plugin_name, 'ios')
      end
    end
  end
end

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

您可以尝试在 Podfile 末尾添加这些行吗：

pod 'Firebase/Auth'
pod 'Firebase/Firestore'
pod 'Firebase/Storage'

您可以在此处查看 Firebase Pod 的完整列表：https://firebase.google.com/docs/ios/setup

或者，您可以添加它们，例如：

 pod 'FirebaseFirestore', :git => 'https://github.com/invertase/firestore-ios-sdk-frameworks.git', :tag => '8.0.0'

你可以直接链接到 GitHub 存储库和你想要的版本（标签），也许使用版本可以解决这个问题。

此外，您可以尝试删除 

Podfile.lock
，然后运行 
pod install
。

我也有同样的问题。我通过将 CocoaPods 更新到最新版本（CocoaPods 1.15.0）来修复它

sudo gem install cocoapods
