Topic on Talk:Download from Git

The "Fetch external libraries" section states that "external libraries that MediaWiki requires are no longer in this "core" git repository".

Which libraries are no longer included?

These instructions are given to install these needed libraries "composer install --no-dev". My understanding of composer is that --no-dev tells composer to skip installing packages listed in require-dev. How then would a command that tells composer to skip installing certain packages cause it to install additional required libraries?

Ah, I hadn't paid attention to the part in the documentation that says "switch to your core directory" before running composer install.

I had been running "composer install" in the project root folder. This folder has a composer.json which requires mediawiki/core.

I see now that there is another composer.json file in the vendor/mediawiki/core folder and that running composer install in this folder brings in additional libraries.

I still don't understand why running composer install at the project root doesn't resolve all dependencies when it installs mediawiki/core.

What is your project root folder? Where did you get this folder from, and why does it have a composer.json that requires "mediawiki/core"??
