Error CS0029 LineRenderer Help

Hi, i have a problem. I started practicing in unity with a tutorial video of unity , Which is called Fun with laser and when to I create the script, appears the following error message: Assets/LaserScript.cs(10,17): error CS0029: Cannot implicitly convert type UnityEngine.LineRenderer[]' to UnityEngine.LineRenderer'

The script contains this:

using UnityEngine; using System.Collections;

public class LaserScript : MonoBehaviour { LineRenderer line;

 void Start () 
 {
     line = gameObject.GetComponents<LineRenderer>();
     line.enabled = false;

     Screen.lockCursor = true;
 }
 

 void Update () 
 {
     if (Input.GetButtonDown ("Fire1")) 
     {
         StopCoroutine("FireLaser");
         StartCoroutine("FireLaser");

     }

 }
 IEnumerator FireLaser()
 {
     line.enabled = true;

     while (Input.GetButton("Fire1")) 
     {
         Ray ray = new Ray(transform.position, transform.forward);
         line.SetPosition(0, ray.origin);
         line.SetPosition(1, ray.GetPoint(100));
         yield return null;
     }

     line.enabled = false;
 }

} I hope you can help me.
