I use the method in Vue element admin to solve the problem that clicking the same menu bar on the side bar does not refresh

// First register a route named `redirect`
<script>
export default {
  beforeCreate() {
    const { params, query } = this.$route
    const { path } = params
    this.$router.replace({ path: '/' + path, query })
  },
  render: function(h) {
    return h() // avoid warning message
  }
}
</script>

Using such a piece of code, an error is reported in my project, and I hide the render function,

However, there is still a warning. Although it does not affect the use, the warning still annoys me,

<template>
  <div>
  </div>
</template>
<script>
// Redirect page, other pages manually trigger a redirect to this page, this page and then return to the original page, in order to achieve the same route to refresh the page effect
export default {
  created() {
    const { params, query } = this.$route
    let { path } = params
    if(path instanceof Array) {
      path = path.join('/')
    }
    this.$router.replace({ path: '/' + path, query })
  },
  // render: function(h) {
  //   return h() // avoid warning message
  // }
}
</script>

In fact, it’s a very simple literal problem. I think Vue element admin is used like this. There is no error reported. I didn’t find Baidu,

Then I suddenly thought of adding a template, which was solved
