Interesting, but I seem to have a problem when requiring the the blackfire-sdk. As it requires the composer/ca-bundle 1.2.7 I get the following error :
"Attempted to call an undefined method named "getName" of class "Composer\CaBundle\CaBundle"

I am running this on a php7.4.6 alpine docker container with composer 1.10.6 on it. (I can give you the link to the github file if you want). My project is based on Symfony 5.0.8 (even though, I guess, this shouldn't matter for blackfire).

I have started looking for composer undefined method errors but have not yet found anything that has something to do with the CaBundle.

Anyway this is not a priority for me for now and the cursus is great ! If anyone has had this issue and knows how to solve it I will be very grateful.

Hey DennisdeBest!

Hmm, very curious! You're totally right that Symfony 5 shouldn't matter. Hmm, if you have the code on GitHub handy, yes, I would love to have it :). We'll want to debug this - because it sounds very odd, could be a bug somewhere - and if you have a setup already handy, that would help.

Thanks!

I made a basic Symfony 5.0.8 website starter that runs on the php:php:7.4.6-fpm-alpine (with some configuration) that works fine at the start but has the error as soon as composer requires the blackfire-sdk. Here is a link : https://github.com/Dennisde... there is more information in the README. Thanks for the quick reply

Hey DennisdeBest!

You found a bug! Well, a few other people have found it also - https://github.com/symfony/... - but nice job! I have just commented on that bug to see if we can "push" a fix forward. For now, if you want to work around, as the comments say, you would need to manually use an older version of symfony/flex.

Cheers!
