Topic on Extension talk:StructuredDiscussions

You should install and run Composer first.

Hi everyone, I'm trying to install StructuredDiscussions on a basically brand new 1.32 MediaWiki instance and receiving the following error:

Command 'php update.php'

failed with return code 255 and error message

PHP Fatal error: Class 'Pimple\Container' not found in

.../extensions/Flow/includes/Container.php on line 5

I've tried running composure update in my root MediaWiki folder, Flow extension folder, etc. as I've seen online and it returns composer command not found.

Do I need to run populateContentModel.php and $wgNamespaceContentModels[namespace] before trying to enable Flow?

I ran populateContentModel.php and $wgNamespaceContentModels[namespace] and am still receiving the same error.

If "composer update" says "composer command not found", you will need to install composer. See installation instructions here.
