用如下podfile:

flutter_application_path = '../flutter_module/'
load File.join(flutter_application_path, '.ios', 'Flutter', 'podhelper.rb')
target 'FlutterHybridiOS' do
  install_all_flutter_pods(flutter_application_path)

  target 'FlutterHybridiOSTests' do
    inherit! :search_paths
    # Pods for testing
  end

  target 'FlutterHybridiOSUITests' do
    inherit! :search_paths
    # Pods for testing
  end

end

pod install 报错：
