vue3+ts quire is not defined

This error typically occurs when you're trying to use a library or module that hasn't been properly imported or installed. In this case, it seems like you're trying to use the `require` function in your Vue 3 + TypeScript project, but it's not defined.

In Vue 3, the `require` function is not available by default. Instead, you should use the ES6 `import` syntax to import modules.

For example, if you want to import the `axios` library, you can do so like this:

import axios from 'axios';

If you're trying to use a module that only provides a CommonJS-style `require` function, you can still use it in your Vue 3 project by installing the `@types/node` package and adding the following line to your `tsconfig.json` file:

{
  "compilerOptions": {
    "types": ["node"]
  }
}

This will allow TypeScript to recognize the `require` function and provide type information for it. However, it's generally recommended to use ES6 `import` statements whenever possible in Vue 3 projects.
