Fixin’ the Error: Step-by-Step Guide

Now that we’ve identified some of the common causes of the “Failed to resolve component” warning, let’s take a step-by-step approach to fixing the error:

Step 1: Check for Typos

The first step is to check for any typos in the component name. Make sure that the component name is spelled correctly and matches the name in the component’s module.

<template>
  <UserBasket></UserBasket>
</template>

<script>
import UserBasket from './UserBasket.vue'

export default {
  components: { UserBasket }
}
</script>

Step 2: Verify Component Registration

Next, verify that the component is registered correctly. Make sure that the component is imported and registered in the correct module.

<script>
import Vue from 'vue'
import App from './App.vue'
import UserBasket from './UserBasket.vue'

Vue.component('UserBasket', UserBasket)

new Vue({
  render: h => h(App)
}).$mount('#app')
</script>

Step 3: Check Module System

Check that the module system is working correctly. Make sure that the component is exported from its module and imported correctly in the application.

// UserBasket.vue
<template>
  <div>User Basket</div>
</template>

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

// main.js
import Vue from 'vue'
import App from './App.vue'
import UserBasket from './UserBasket.vue'

Vue.component('UserBasket', UserBasket)

new Vue({
  render: h => h(App)
}).$mount('#app')
</script>

Step 4: Verify Component Export

Finally, verify that the component is exported from its module. Make sure that the component is exported using the `export default` syntax.

// UserBasket.vue
<template>
  <div>User Basket</div>
</template>

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