The error message "export 'Vue' (imported as 'Vue') was not found in 'vue'" indicates that there might be an issue with how you are importing the Vue object from the vue package.

To resolve this issue, you can try the following steps:

1. Make sure you have installed the vue package as a dependency in your project. You can do this by running the following command in your project directory:

   npm install vue

2. Verify that you are importing the Vue object correctly in your code. The import statement should look like this:

   import Vue from 'vue';

3. Ensure that you are using the correct version of Vue. In newer versions of Vue (version 3 and above), the way to create a Vue instance has changed. Instead of using the `Vue` object, you can directly create a new app instance using `createApp`. Here's an example:

   import { createApp } from 'vue';
   const app = createApp({
     // your app configuration options go here
   });

If the issue persists or you are using an older version of Vue, please provide more details about your code and how you are importing and using Vue so that I can assist you further.
