The component cannot be found in vue3.0 or the corresponding type declaration cannot be found. How to deal with it

How to solve the problem that the component cannot be found in vue3.0 or the corresponding type declaration cannot be found?

• Here is the error, the reason for the error
• Error reporting is the impact of ts
• The component module could not be found or the corresponding type declaration could not be found
• Typescript can only understand .ts files, not .vue files
• 
• Solution
  Create a file with the suffix .d.ts in the project root directory or src folder, and write the following content:

•  declare module '*.vue' {
        
        
     import {
        
         ComponentOptions } from 'vue'
     const componentOptions: ComponentOptions
     export default componentOptions
   }

• Of course the name is arbitrary
• Many people think that saving is enough => just restarting the project
  requires ctrl+c to terminate the project and restart the project
