l have been having this on my script error CS8025: Parsing, l don't what to do

Remove the ending curly brace before the spawnEnemies method, this is closing the class and thus your error.

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 
 public class Differentball : MonoBehaviour
 {
     public GameObject[]spawnPoints;
     public GameObject Enemy;
     public Text countText;
 
     private int count;
 
 
     // Use this for initialization
     void Start () 
     {
         spawnPoints = GameObject.FindGameObjectsWithTag("spawn");
         count = 0;
         SetCountText ();
     }
     
     // Update is called once per frame
     void Update ()
     {
         
         GameObject[] enemies;
         enemies = GameObject.FindGameObjectsWithTag ("Enemy");
 
         if (enemies.Length >= 3) {
             print ("too many enemies on the dance floor");
         }
         else 
         {
             InvokeRepeating ("spawnEnemies", 1, 4f);
             count = count + 1;
             SetCountText ();
         }
     }
 
     void SetCountText ()
     {
         countText.text = " count ; " + count.ToString ();
     }
 //} <--------------------------REMOVE ME AS I CLOSE THE CLASS DEFINITION leaving the method spawnEnemies crying in the corner wondering why no class wants it.
     void spawnEnemies ()
 
         int SpawnPos = Random.Range (0, (spawnPoints.Length - 0));
 
         Instantiate (Enemy, spawnPoints [SpawnPos].transform.position, transform.rotation);
         CancelInvoke ();
     }
