iOS中的颤振音频服务依赖性问题

我正在添加后台运行音频的程序包。在安卓系统中它可以工作，但作者并没有在iOS中实现，所以在iOS中运行应用程序时会出现以下错误

错误：

# Uncomment this line to define a global platform for your project
# platform :ios, '9.0'

# CocoaPods analytics sends network stats synchronously affecting flutter build latency.
ENV['COCOAPODS_DISABLE_STATS'] = 'true'

在调试模式下在iPhone 8 Plus上启动lib/main.dart。。。 正在运行pod安装。。。 椰子荚的产量： ↳ 准备

运行pod安装时出错 在iPhone 8 Plus上启动应用程序时出错

下面是pod文件：

# Uncomment this line to define a global platform for your project
# platform :ios, '9.0'

# CocoaPods analytics sends network stats synchronously affecting flutter build latency.
ENV['COCOAPODS_DISABLE_STATS'] = 'true'

}

def parse_KV_file(file, separator='=')
  file_abs_path = File.expand_path(file)
  if !File.exists? file_abs_path
    return [];
  end
  pods_ary = []
  skip_line_start_symbols = ["#", "/"]
  File.foreach(file_abs_path) { |line|
      next if skip_line_start_symbols.any? { |symbol| line =~ /^\s*#{symbol}/ }
      plugin = line.split(pattern=separator)
      if plugin.length == 2
        podname = plugin[0].strip()
        path = plugin[1].strip()
        podpath = File.expand_path("#{path}", file_abs_path)
        pods_ary.push({:name => podname, :path => podpath});
      else
        puts "Invalid plugin specification: #{line}"
      end
  }
  return pods_ary
end

target 'Runner' do
  # Prepare symlinks folder. We use symlinks to avoid having Podfile.lock
  # referring to absolute paths on developers' machines.
  system('rm -rf .symlinks')
  system('mkdir -p .symlinks/plugins')

  # Flutter Pods
  generated_xcode_build_settings = parse_KV_file('./Flutter/Generated.xcconfig')
  if generated_xcode_build_settings.empty?
    puts "Generated.xcconfig must exist. If you're running pod install manually, make sure flutter packages get is executed first."
  end
  generated_xcode_build_settings.map { |p|
    if p[:name] == 'FLUTTER_FRAMEWORK_DIR'
      symlink = File.join('.symlinks', 'flutter')
      File.symlink(File.dirname(p[:path]), symlink)
      pod 'Flutter', :path => File.join(symlink, File.basename(p[:path]))
    end
  }

  # Plugin Pods
  plugin_pods = parse_KV_file('../.flutter-plugins')
  plugin_pods.map { |p|
    symlink = File.join('.symlinks', 'plugins', p[:name])
    File.symlink(p[:path], symlink)
    pod p[:name], :path => File.join(symlink, 'ios')
  }
end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['ENABLE_BITCODE'] = 'NO'
    end
  end
end

在这里，如果p[：name]！='音频服务“

# Plugin Pods
  plugin_pods = parse_KV_file('../.flutter-plugins')
  plugin_pods.map { |p|
    if p[:name] != 'audio_service'
      symlink = File.join('.symlinks', 'plugins', p[:name])
      File.symlink(p[:path], symlink)
      pod p[:name], :path => File.join(symlink, 'ios')
    end
  }

但是没有起作用

我如何解决这个问题？我们可以在subspace.yaml文件中设置限制吗？像这样的依赖只安装在android平台上？总之，我只是想修复它。

只要删除你的

ios/Podfile.lock

文件，然后在同一个目录下运行

pod install

你应该可以走了。这将确保您使用的是正确的版本。

您尝试过这个吗？我试过了，但没有帮到我。事实上，这个插件还不仅仅适用于iOS@CopsOnRoad是的，你是对的，我不想在iOS中使用这个插件，只想在android上使用。因为我用的是另一个。那么我怎样才能在iOS中避免这个错误呢。以及我们可以在pubspec.yaml文件或任何其他方式中应用的条件？RE：我们可以在subspace.yaml文件中设置限制吗？没有办法做到这一点，但假设没有编译错误，您的Android应用程序将不包含任何iOS代码/插件，反之亦然。它将只使用任何本机Dart代码加上相应平台的lib/代码（包括插件）构建应用程序，不包括其他任何应用程序。

pod install
