unity自动添加头注释代码后无法创建新脚本
我在Editor文件夹下创建了脚本，内容如下：
using UnityEngine;
using UnityEditor; // 被继承的类所在的命名空间
using System.IO; // IO文件操作命名空间
using System; // C#基础功能命名空间
using System.Text.RegularExpressions; // 正则表达式的命名空间
public class SCHead : UnityEditor.AssetModificationProcessor
{
private static void OnWillCreateAsset(string path)
{
path = path.Replace(".meta", ""); // 这里跌path是你的项目主路径Asset/Scripts/文件名
if (path.EndsWith(".cs")) // 判断是否是c#文件
{
string fileName = Regex.Match(path, @"[^/]*$").Value; // 通过正则拿到仅含文件名的字符串
string str = File.ReadAllText(path); // 获取创建的文件名的全部内容
str = str.Replace("#Name#", "yyy").Replace("#CreateTime#", DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")).Replace("#FileName#", fileName).Replace("#path#", path); // 将头部注释替换
File.WriteAllText(path, str); // 将替换后的内容写入文件，将原内容覆盖
AssetDatabase.Refresh();
}
}
}
然后再创建新脚本时，就不能再创建了，提示报错如下，请问如何解决：
