javascript - Vue router with Vue 3 raises the error "Uncaught TypeError: Object(...) is not a function"

Question

Created a simple Vue project using the CLI:

vue create my-project

Wanted to add two pages, so installed the latest version of vue-router (which is currently v3.4.8) and followed the vue mastery tutorial for routing.

This is what my router.js file looks like:

import { createWebHistory, createRouter } from 'vue-router'
import Home from './components/Home.vue'
import About from './components/About.vue'

const router = createRouter({
  history: createWebHistory(),
  routes: [
    { path: '/', name: 'Home', component: Home },
    { path: '/about', name: 'About', component: About },
  ]
})

export default router

And of course, this is what my main.js file looks like:

import { createApp } from 'vue'
import router from './router'

createApp({
  template: `
  <div>
    <router-link to='/'>Home</router-link>
    <router-link to='/create'>Create</router-link>
  </div>
  `
})
.use(router)
.mount('#app')

Both of the Home and About components don't really have much in them, this is what they look like:

<template>
  <div>TODO: Home</div>
</template>

<script>
  export default {
    name: 'Home'
  }
</script>

Anyway, all of this to say that I am getting the following error on:

Uncaught TypeError: Object(...) is not a function

at eval (router.js?41cb:5)

This is specifically on createRouter

Have I done something wrong?

Edit: as Boussadjra Brahim pointed out, originally createWebHistory was just being passed in without being a function call. I've since updated the code to include this.

Interestingly enough, once that was done, the error is not happening upon it's call.

This issue is caused when you install Vue router 3 with Vue 3 so you should uninstall the current version :

npm uninstall vue-router --save

and install the new one by :

npm i vue-router@next --save
