这是我的组件。
el.focus()插入时确实有效，但我进入[Vue warn]: Property or method "v" is not defined on the instance but referenced during render了控制台。如何去除警告？
<script>
export default {
directives: {
focus: {
inserted (el) {
el.focus()
}
}
}
}
</script><style lang="stylus" scoped>
input
width: 300px
height: 30px
border: 1px solid #000
</style>
<template lang="jade">
div
input(v-focus)
</template>
