Question: Unable to install pods (0.91.1) could not find compatible versions for pod "Flipper-Folly"

Hi!

I was recently trying to add Flipper to my react-native app, followed by this instruction https://fbflipper.com/docs/getting-started/react-native-ios#initialization

so my Podfile looks like this:

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

platform :ios, '14.5'

target 'MyApp' do
  config = use_native_modules!

  use_react_native!(
    :path => config[:reactNativePath],
    # to enable hermes on iOS, change `false` to `true` and then install pods
    :hermes_enabled => true
  )

  target 'MyAppTests' 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 these next few lines.
  # use_flipper!()
  use_flipper!({'Flipper' => '0.91.1'}) # should match the version of your Flipper client app

  pre_install do |installer|
     $RNMBGL.pre_install(installer)
  end

  post_install do |installer|
    flipper_post_install(installer)

    $RNMBGL.post_install(installer) # MapBox required
    react_native_post_install(installer)
  end
end

after running pod install I am getting an error:

[!] CocoaPods could not find compatible versions for pod "Flipper-Folly":
  In Podfile:
    Flipper (= 0.91.1) was resolved to 0.91.1, which depends on

Thanks for help!

@Nodman I think you don’t need to use flipper_post_install(installer) because react_native_post_install(installer) already does it.

I’m using like this and it’s working:

use_flipper!({ 'Flipper' => '0.91.1', 'Flipper-Folly' => '~> 2.6', 'Flipper-RSocket' => '~> 1.4' })

passing ‘Flipper-Folly’ 2.6 version explicitly did the trick, should have look into example first 😕 this probably needs to be added to rect-native docs though

Thanks you for your time and help guys, closing this.
