[02:08:59] <JMJimmy>	 hey all - I've been trying to install semantic mediawiki & related extensions - however I've run into an error I can't seem to make sense of.... PHP Fatal error:  Class 'Composer\Semver\VersionParser' not found in /home/usr/public_html/wiki/includes/registration/CoreVersionChecker.php on line 42 (occurred after running composer update)
[03:19:51] <JMJimmy>	 ugh - figured it out.  composer.local.json files aren't supported by Composer 1.1.1 so in creating a composer.json file it conflicted with the /vendor/composer.json so Composer 1.4.2 is required (or whatever version they added .local.json to)
