Wired PackageManager Error

I met a problem but I can still run my game:

System.MissingMethodException: Method not found: 'UnityEditor.PackageManager.Client.List'. at (wrapper managed-to-native) System.Reflection.MonoMethod:InternalInvoke (object,object[],System.Exception&) at System.Reflection.MonoMethod.Invoke (System.Object obj, BindingFlags invokeAttr, System.Reflection.Binder binder, System.Object[] parameters, System.Globalization.CultureInfo culture) [0x000d0] in /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.Reflection/MonoMethod.cs:222 UnityEditor.EditorAssemblies:ProcessInitializeOnLoadAttributes()

What may cause such a problem? I copied some asset from another project built in 2018.2. How can I fix this problem? It pops up every time when I compile or run my game.
