使用LinValidator报错

[keweixun01]

定义：
const { Rule, LinValidator } = require('lin-mizar')
class test extends LinValidator{
constructor(){
super()
this.test =[
new Rule('isInt','测试')
]
}
}
module.exports = {test}
使用：
router.get('/:test/error',(ctx,next)=>{
const res = new Test().validate(ctx)
console.log(res)
})
报错：

throw new Error('CodeMessage.getMessage() must be implemented');
