whenever i try to launch fabric this is what pops up and i cant find a way to fix it.

It seems like you are using the 1.15 version of fabric on possibly 1.14?

I had the same issue with the 1.14 version of Fabric. Make sure you have the correct version of the Fabric API, I accidentally had the 1.15.1 version of the Fabric API and when I replaced it with the 1.14.4 version it was fixed.

If you have any more issues with this, please re-open or create a new issue.

So, i had 1.15 fabric and i had fabric api and voxel map in the mods folder. To make fabric 1.16 work i had to delete 1.15 mods and replace them

what is this?
how to fix it?
i wanna play with a fabric mod.
HELP!!!

I am having the same issue.

I am having the same issue. I will attempt a reinstall.

Reinstall did not resolve issue.

The message is a dependency error, the one in the topic means that fabric-api (as available from CurseForge) needs any 1.15 Minecraft version after 19w42a, but that wasn't the case. It was running 1,13, 1.14, 1.16, some older 1.15 snapshot - none of which are suitable for the installed fabric api version.

You also want to use a recent Fabric Loader version.
