requires version X of Y, which is missing
COAL-019 · Specific missing mod dependency
A Fabric mod needs a specific version of another mod that is not installed. How to read the requirement line and install the right build.
What it looks like in the log- Mod 'Some Mod' (somemod) 1.2.0 requires version 0.92.0 or later of fabric-api, which is missing!
What it means
Fabric Loader is listing an unmet requirement, and the line contains everything you need: which mod is complaining (Some Mod), what it needs (fabric-api), and which versions would satisfy it (0.92.0 or later). "Missing" can mean not installed at all, or installed at a version outside that range.
How to fix it
- Install the named mod at a version inside the stated range, built for your exact Minecraft version.
fabric-apiis by far the most common one to be missing - a large share of Fabric mods depend on it. - If it is already installed, update it - and delete the old jar rather than leaving both, or you will land on COAL-008 next.
- Or remove the requesting mod if you would rather not add the dependency.
- Expect several of these at once. Read the whole list and fix every line before restarting.
