When I have tried to install laravel 8 via composer for on localhost MAMP

I have gotten this message in command line (terminal): -bash: /Applications/MAMP/bin/php/php7.4.16/bin/php: No such file or directory

notice php7.4.16 shows in path, although I'm using ver 8, further to, this version is no longer supported and not in use at all.

I had searched for solving my problem in google, until I found some treatment for solving path issue, but it doesn't benefit me:

_export PATH="/Applications/MAMP/bin/php/php7.0.27/bin:${PATH}" _

it has replaced the php ver path I have actually, but the problem is still.

why this version shows in my installation path although it's old & dead version?

what I should do?

kindly, anybody could help me to solve this problem?

Also, could me to install composer on XAMPP instead of MAMP, because I have a copy of it on my MacBook computer already?

Thank you for my helping in advance.
