iOS - CocoaPods requires your terminal to be using UTF-8 encoding - after latest flutter upgrade

Question

I am getting this error after I upgraded flutter. Before upgrading everything was working normal on both iOS and android. Now my project is not building in iOS.

Below is my terminal info.

pod setup --verbose

    WARNING: CocoaPods requires your terminal to be using UTF-8 encoding.
Consider adding the following to ~/.profile:

export LANG=en_US.UTF-8

pod install --verbose

WARNING: CocoaPods requires your terminal to be using UTF-8 encoding.
Consider adding the following to ~/.profile:

export LANG=en_US.UTF-8

[!] No `Podfile' found in the project directory.

LC_ALL=

Answer 1

open Terminal type open ~/.zshrc (or .profile if you don't use zsh)

It seems that LANG="en_US.UTF-8" alone isn't enough, you have to set

export LANG=en_US.UTF-8
export LANGUAGE=en_US.UTF-8
export LC_ALL=en_US.UTF-8

save the file

go back to Terminal

type source ~/.zshrc

type locale

You can now safely run pod update or pod install

Answer 2

After one day of struggle finally i found the full solution

Follow these steps to solve this issue

1. Unhide filles in Mac using Cmd + Shift + dot.
2. Go to Macintosh HD -> User -> (Your user ).
3. Search for .zshrc
4. Open it with any editor (I recommend VS code)
5. Under. #User configuration comment out export LANG=en_US.UTF-8.
6. Open your flutter project and manually delete Pods folder, Podfile, Podfile.lock. (back-up all podfiles)
7. Restart your Mac and run your flutter application
8. Run pod install
9. It will automatically create podfile and its new config in UTF - 8 encoding
10. Enjoy and chill i got your back !!!!!
