vue项目报错：说在“hasChildren”计算属性中返回值时出现错误，有点没搞懂，求解答

91:19 error Expected to return a value in "noChildren" computed property vue/return-in-computed-property
94:20 error Expected to return a value in "hasChildren" computed property vue/return-in-computed-property

代码截图如下：

求解答感谢！

你没return出来
computed计算属性需要把值retrun出来
