Problem with Magento install on MAMP

I’ve been trying to install Magento(2-2.4) on MAMP Pro on my macbook downloaded the code and manual install and I’ve gotten close but I can’t figure out how to get past this screen:

enter image description here

There was no version set in the composer.json file so I tried “version”: “2-2.4” and “version”: “2.2.4” and I get the same result. Do I need to start over or am I overlooking something?

I apologize if this is a repost, I haven’t been able to find anything and there’s nothing in the error logs.

Thanks in advance for any help.
