mediawiki/maps[11.0.0, 11.0.1] cannot be installed

[redheadkelly]

I'm simply trying to copy an install of MediaWiki that works into a different directory. I copied all the files and updated the LocalSettings.php to the correct database info. But I'm still having problems getting it to work.

Maps is a great extension and a pivotal part of my wiki, but it seems to be the one thing that gives me problems every single time I upgrade. Is there a secret? Some trick I'm missing?

This time I'm getting...

Problem 1 - mediawiki/core is present at version 1.0.0+no-version-set and cannot be modified by Composer - Root composer.json requires mediawiki/maps ~11.0 -> satisfiable by mediawiki/maps[11.0.0, 11.0.1]. - mediawiki/maps[11.0.0, 11.0.1] cannot be installed as that would require removing mediawiki/core[1.0.0+no-version-set]. They both replace mediawiki/semantic-maps and thus cannot coexist.

MediaWiki version is 1.43.1.
PHP 8.3.28 (litespeed)
ICU 64.2
MySQL 8.0.33-cll-lve
LuaSandbox 4.1.2
Lua 5.1.4
Pygments 2.17.2
Semantic MediaWiki 5.0.0

I would suggest redoing the Composer intallation. There might be something wrong with the vendor directory.

Basically just Step 1 of https://maps.extension.wiki/wiki/Installation#Step_1.2F2:_composer_update
