Hi @brainy-translator-85865 Which version of yarn are you using? It looks like you could be using Yarn Modern, not Yarn Classic. If I guessed right then try the following:

Copy code

yarn set version classic
yarn install
yarn dev

Edit: See also https://github.com/cypress-io/cypress-realworld-app/pull/1337 for proposed addition to README documentation.

It will not work with Yarn 3. You need Yarn 1 (Classic).

You should be seeing this in your logs:

Copy code

$ yarn set version classic

You may have Yarn 3 parts in your repository copy which prevent resetting to Yarn 1.

git status

may show what has been added. I suggest you reset the example repository or simply delete it and clone it again, then try again.

If you would like to try out an example repository which does not use `yarn`then you can use https://github.com/cypress-io/cypress-example-kitchensink instead. This only needs

npm
