Thread:Project:Support desk/Unable to install Language Extension Bundle

I followed the tutorial to install. I used the first layout. When I run the following command, php maintenance/update.php It shows error: MediaWiki 1.22.3 Updater DB connection error: No such file or directory (localhost) When I go to following: my_local_site/mediawiki/mw-config/ It end up with error and call stack:

Can you please help me fix the error and install the language extension onto my mediawiki? I am running my local XAMPP on mac osx 10.
