I am using cake php 2.9 . Now I am trying to migrate it into 3.9 . When I run php composer.phar require --update-with-dependencies "cakephp/cakephp:3.9.*" it show's Could not open input file: composer.phar
It is noted that my os is windows 10 and php version is 7.1.
Is there any dependency If I migrate this ? Thanks in advance
My ultimate target is to go to php 7.1
