Missing dependenciesMod requires Fabric API but it is not installed
What the log looks like
requires (?:any version of )?fabric(?:-?api)?, which is missing
requires any version of mod 'fabric'
fabric api[^\n]{0,60}(?:is )?(?:not installed|missing)
How to fix it
- Download Fabric API for the exact Minecraft version you are launching
- Put the Fabric API jar in the same mods folder, do not rename it
- Fabric API is one jar per Minecraft version — a 1.20.1 build will not load on 1.21
