The error “Could not find required mod: requires {fabric @ [*]}” appears when running Minecraft with mods that use the Fabric loader. It means that the mods folder does not contain the required technical mod - Fabric API.

This library is required for most Fabric mods to work. Sometimes instead of [*] the message contains a specific minimum version, e.g. fabric-api @ [0.41.0,), which indicates the required API version.

The solution is simple:

• Go to the Fabric API page on ModLand.

• Download the latest version that matches your version of Minecraft.

• Place the .jar file in the .minecraft/mods folder.

After that, restart the game - the error will disappear and the mods will start working correctly.
