我已经准备好进行游戏，并且在构建时遇到CS0012错误。
error CS0012: The type 'UnityEngine.MonoBehavior' is defined
in an assembly that is not referenced. Consider adding a reference to assembly
'UnityEngine, Version=0.0.0.0,Culture=neutral,PublicKeyTiken=null'
我正在使用Unity 2018.1.9f1，使用Scripting Runtime Version .NET 4.x等效版本构建Android 8.0，Scripting Backend是Mono，API兼容级别是.NET 4.x
