Hi @SL-BLACK-EAGLE. You're getting this issue because you're using the version of Ruby that came preinstalled on your Mac. The most reliable way to install Cocoapods on a Mac is to set up a proper Ruby development environment that uses a version manager to install a newer and separate version of Ruby that doesn't interfere with the system Ruby. Once you have that, installing a new React Native application should work.

Here's a very detailed step-by-step guide for installing Ruby on a Mac.

HI @monfresh. First of all I would like to thank you very much and appreciate your prompt response for the issue i have created.
I have read your comment as well as the document you have linked. i have read all the details and in the document top to bottom step by step. It’s very helpful to me. i have follow the steps as per the instructions. and finally i have successfully created the React native application by react native CLI command. i have spend many times to solve it and it all the time it’s failed. but you have solved and save my time in one Response. Thank you for your support.

At some point, i happened to enable rosetta for terminal(which I totally forgot about later). This is a life saver @monfresh . This is just brilliant. Saved a lot of my time!
