The project seems to require pnpm but it's not installed.

To install pnpm, you can follow these steps:

1. Make sure you have Node.js installed on your system. You can check if Node.js is installed by running `node -v` in your terminal. If it's not installed, you can download and install it from the official Node.js website (https://nodejs.org).

2. Once Node.js is installed, you can install pnpm globally by running the following command in your terminal:

   npm install -g pnpm

3. After the installation is complete, you can verify if pnpm is installed by running `pnpm -v` in your terminal. If it displays the version number, then pnpm is successfully installed.

Now you should be able to use pnpm for your project. Let me know if you have any further questions!
