Was trying to setup Android Studio and flutter on my Intel Mac. Did not face this issue when using the Apple silicon Mac.

Actual Error Message

Steps to resolve:

Step 1: Install active support gem

sudo gem install activesupport -v 6.1.7.3

I have to run the above command as prompted before installing cocoapods as it prompts that my Ruby is outdated.

ERROR:  Error installing cocoapods:

The last version of activesupport (>= 5.0, < 8) to support your Ruby & RubyGems was 6.1.7.3. Try installing it with `gem install activesupport -v 6.1.7.3` and then running the current command again

activesupport requires Ruby version >= 2.7.0. The current ruby version is 2.6.10.210.

After successfully executed the command, I see that 2 gems was installed.

Console output for install activesupport -v 6.1.7.3

Step 2: Install cocoapods

Next I proceed with the installation of cocoapods:

sudo gem install cocoapods

Message after successful installation of cocoapods

Step 3: Rerun Flutter doctor

After rerunning flutter doctor, all looks good!
