Help with old installation

I’m doing a development upgrade and we need to pre-production a 1.0.0 environment to upgrade to the latest version, and we’re having issues with mimemagic on 0.3.0
Could you help me with this?

Hi, @wdwertos (I take it you’re also @Alesander, right?).

I think I’ve already answered your question :thinking:. Check the part talking about modifying the Gemfile.lock: Problem installing in new development environment for v1.0.0

@wdwertos Sorry, thought you had published your question before I had already answered the other one because I’ve received the notification today :pray:. I’ve just realized that wasn’t the case :ok_hand:.
