How to fix Error Failed to update CocoaPods repositories for iOS project (React Native on Mac OS)

On my MacBook Pro with Apple M1 Pro and macOS Monterey (12.4), I got the following error message when creating an React Native project.

Updating CocoaPods repositories (this may take a few minutes)

error Error: Failed to update CocoaPods repositories for iOS project.

Ckeck the Xcode Command Line Tools

Open Xcode

Go to Preferences -> Locations and choose the Command Line Tools if the dropdown menu is empty.

xcode comand line tools

Install CocoaPods via pod command fails

cd MyReactNativeProject
cd ios
pop install

or

cd MyReactNativeProject
cd ios
ios % pod repo update

The two commands also throw an error message.

Error

LoadError - dlopen(/Library/Ruby/Gems/2.6.0/gems/ffi-1.15.5/lib/ffi_c.bundle, 0x0009): tried: '/Library/Ruby/Gems/2.6.0/gems/ffi-1.15.5/lib/ffi_c.bundle' (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64e')) - /Library/Ruby/Gems/2.6.0/gems/ffi-1.15.5/lib/ffi_c.bundle
[!] CocoaPods could not find compatible versions for pod "FlipperKit/FlipperKitUserDefaultsPlugin":
  In Podfile:
    FlipperKit/FlipperKitUserDefaultsPlugin (= 0.125.0)

None of your spec sources contain a spec satisfying the dependency: `FlipperKit/FlipperKitUserDefaultsPlugin (= 0.125.0)`.
Searching for inspections failed: undefined method `map' for nil:NilClass

Initialization of the React Native project with a given architecture (arch -x86_64) also does not work

arch -x86_64 npx react-native init cd MyReactNativeProject
Error: Failed to install CocoaPods dependencies for iOS project, which is required by this template.

Solution

Delete the CocoaPods resositories and create the project

sudo rm -rf ~/.cocoapods/repos
npx react-native init cd MyReactNativeProject

cd ./cd MyReactNativeProject/ios && pod install
Pod installation complete! There are 55 dependencies from the Podfile and 46 total pods installed.

And success.
