Problem setting up fork to provide contributions #2072
Description
I'm trying to set up a fork of this project so that I can contribute back to it (this is my first attempt at contributing back so this might be considered a general problem, rather than a specific "create-react-app" problem - but since I want to contribute to this project I thought I'd raise it here).
I've looked at the contributing guide and have forked (rather than cloned as suggested although I don't think that should make a difference) the repository.
I've built the project using npm install (which is successful).
However, when running npm run create-react-app my-app as suggested I get the following error output:

Am I doing something wrong here or is there an issue with the contribution instructions?
