Been awhile since I’ve popped in here but with some good news (and another question) I finally got haxeui working on my machine. I think I have a vague idea of what went wrong but I’m not entirely sure it’s correct. Basically what I did for anyone that had similar issues was manually remove the packaged release of haxeui-core that gets automatically downloaded when using haxeui-flixel. What I should have done was leave that be and manually use haxelib set to just change to the git version. It seems like something went wrong when trying to remove the old packaged version where maybe it didn’t actually switch to git even though it was showing git as being selected. Use haxelib set and it seems to work fine. A whole lot of tinkering for what ended up being a super simple solution.
