If you are encountering the error "koa2 not found", it means that the Koa2 module is not installed in your project.
You can install Koa2 using the following steps:
1. Open your project directory in the command line interface.
2. Run the following command to install Koa2:
```
npm install koa
```
This will install the latest version of Koa2 in your project.
3. Once the installation is complete, you should be able to import and use Koa2 in your project.
For example, if you want to use Koa2 in a file named `app.js`, you can import it using the following code:
```
const Koa = require('koa');
const app = new Koa();
```
This will import Koa2 and create a new instance of the Koa application.
I hope this helps! Let me know if you have any more questions.
