You cannot use Ext.Create while defining class.

You have to use initComponent method in which you can assign config using Ext.Create.

Ext.define('MyApp.view.library.LibraryTreeView', {
       extend : 'Ext.tree.Panel',
       alias : 'widget.librarytreeview',
       requires: [
         'MyApp.store.LibraryFolderTreeStore'
       ],
       initComponent : function(){
       this.store = Ext.create("MyApp.store.LibraryFolderTreeStore");
       this.callParent();
       }
        // getting error on this line
       ....
});
