cypress-io / cypress-realworld-app

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!
