Compilation error 7 Days To DieError

Hello. I can't upload the plugin to my 7 DTD server. I get the following error:

Oxide.Game.Rust is referenced by PlaceholderAPI plugin but is not loaded
[CSharp] Started Oxide.Compiler v1.0.22.0 successfully
Ignored unexpected plugin compilation failure: PlaceholderAPI
Error while compiling PlaceholderAPI: The type or namespace name 'Rust' does not exist in the namespace 'Oxide.Game' (are you missing an assembly reference?) | Line: 28, Pos: 18
Shutting down compiler because no more jobs
Compiler shutdown completed

Could you help me?
