Vue.js Error: Cannot read properties of undefined (reading 'use') - How to Fix

This error occurs because the code is trying to access the 'use' property of an undefined object. The error message indicates that the issue is in line 12 of the 'index.js' file in the router folder.

To fix this error, you need to make sure that the object being accessed has a 'use' property defined. You can do this by checking if the object exists before trying to access its properties.

Here's an example of how you can modify the code to handle this error:

import { createRouter, createWebHistory } from \'vue-router\';
import Home from \'../views/Home.vue\';

const routes = [
  {
    path: \'/\',
    name: \'Home\',
    component: Home,
  },
];

const router = createRouter({
  history: createWebHistory(process.env.BASE_URL),
  routes,
});

// Check if the router object exists before using it
if (router) {
  router.use(/* ... */);
}

export default router;

By adding the conditional statement to check if the router object exists, you can prevent the error from occurring when trying to access the 'use' property.
