Reactnative pod installe error Invalid `Podfile` file: undefined method `get_default_flags' for #<Pod::Podfile...>

我使用 React Native,今天我 运行 pod 安装并收到此错误: [!] 无效 Podfile 文件:#Pod::Podfile:0x00007f89a2d98d38 的未定义方法“get_default_flags”。

这是我的 pod 文件:

require_relative '../node_modules/react-native/scripts/react_native_pods'
require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'

platform :ios, '11.0'
install! 'cocoapods', :deterministic_uuids => false

target 'MyPrj' do
  config = use_native_modules!

  # Flags change depending on the env values.
  flags = get_default_flags()

  use_react_native!(
    :path => config[:reactNativePath],
    # to enable hermes on iOS, change `false` to `true` and then install pods
    :hermes_enabled => flags[:hermes_enabled],
    :fabric_enabled => flags[:fabric_enabled],
    # An absolute path to your application root.
    :app_path => "#{Pod::Config.instance.installation_root}/.."
  )




  pod 'RNVectorIcons', :path => '../node_modules/react-native-vector-icons'

  target 'MyPrjTests' do
    inherit! :complete
    # Pods for testing
  end

  # Enables Flipper.
  #
  # Note that if you have use_frameworks! enabled, Flipper will not work and
  # you should disable the next line.
  use_flipper!()

  post_install do |installer|
    react_native_post_install(installer)
    __apply_Xcode_12_5_M1_post_install_workaround(installer)
  end
end

我不知道为什么会出现这个,谁能指导我解决这个问题?谢谢

遇到这个问题的各位,只需将package.json中的react-native更新为^0.68.0
