on running rbenv install 2.7.6 it shows like this

Answer 1

When you are creating a project. By default it get created at react-native latest version whihch is 0.71 requires a ruby version of 2.7.6 .

You have to install the ruby of that specific version. You can install it by following this link

Answer 2

The error is fairly self explanatory. I'll assume that Ruby 2.7.6 is not installed. To install the Ruby version run:

rbenv install 2.7.6

Once installed update the version you're using. Assuming you're in your project folder you can update the local version by changing the .ruby-version file. This can be done with a rbenv command as well:

rbenv local 2.7.6

Which will update the .ruby-version file for you (assuming that you're in the correct working directory).

Finally validate that the new Ruby version is installed and in use.

ruby --version

Should print 2.7.6
