I've tried multiple times and getting a Typescript error while starting the application. Please see the error below.

• What is your operating system? Windows x?
• Which version of Node.js are you using? 20.11.0
• Which command did you run? yarn dev?
• Have you modified your clone of the example repo https://github.com/cypress-io/cypress-realworld-app and / or installed any different versions of dependencies?

I am not seeing any errors on Windows 11 with Node.js 20.11.0

git clone https://github.com/cypress-io/cypress-realworld-app
cd cypress-realworld-app
npm install yarn@latest -g
yarn
yarn dev

This is the normal log of yarn dev on Windows 11:

I have the following:
Windows 11
Node 18.13.0
Yar 1.22.22

Yes, I ran Yarn dev command. I cloned the repo from Git.

@naeemakram

You say you are using Node.js 18.13.0. The README says:

This project requires Node.js to be installed on your machine. Refer to the .node-version file for the exact version.

cypress-realworld-app/.node-version

Line 1 in b83b071

20.11.0

so you should update Node.js to the requested version. I don't know if that will resolve your issue though as I am not able to reproduce it. Good luck!
