Question

PHP

composer instalError occurs while executing

it is missing from your system. Install or enable PHP's imap extension.

Tell me, if I can solve it simply --ignore-platform-req=ext-imap- is it critical? Or tell me what to do. Thank you!

Answer 1

It is necessary, as it is said, to install the php imap extension , which is intended for working with servers using the appropriate protocol. For mautic, it is certainly necessary.
But why you need to install mautic locally is not entirely clear. Usually it is installed on the hosting.
