Failed to install CocoaPods dependencies for iOS project React-Native - ios

Question

So I tried to use react-native on my brand new MacBook but I'm having some issues.
(I'm on MacOs BigSur Version 11.2.2 with a M1)
I followed the step on the environnement setup on react native website.
brew install node
brew install watchman
Installed Xcode and went to preferences > location > Command line tools > Xcode 12.4 (12D4e)
sudo gem install cocoapods
Then, I tried to do : npx react-native init tesr (I misspelled test and wrote tesr but I guess it's not really important).
and here I got this error :
✖ Installing CocoaPods dependencies (this may take a few minutes)
✖ Installing CocoaPods dependencies (this may take a few minutes)
error Error: Failed to install CocoaPods dependencies for iOS project, which is required by this template.
Please try again manually: "cd ./tesr/ios && pod install".
So, I try cd ./tesr/ios && pod install and I see this :
### Command

[!] Oh no, an error occurred.
Even if there was an error, I wanted to try to run-ios, it obviously didn't worked, and then I went on some other stackOverflow page that got the same problem than me and couldn't solve my problem.
I'm new to macOS and apple product so I'm probably really bad at this but yeah if you have something that can help, I'll try it.

Answer 1

You may also add the following configuration in the .zshrc file:
export LANG=en_US.UTF-8
export LANGUAGE=en_US.UTF-8
export LC_ALL=en_US.UTF-8
NOTE: Restart you mac after you add this configuration.
After Restarting, Just use your terminal to run these commands.
1) brew install libffi
2) brew install cocoapods
Then it is done.
If you face any error around null safety, you can run the following command in the terminal to launch you app.
flutter run --no-sound-null-safety
This has solved my issue and is working fine. Hope it helps

Answer 2

I found a way to make it work, you just need to install Rosetta !
