### Bug Description

To develop on strapi core files, I follow the Development Workflow steps in the CONTRIBUTING.md file (https://github.com/strapi/strapi/blob/develop/CONTRIBUTING.md). 

When I run yarn install and then yarn setup, I get a series of errors in the build section. I think that's why when I do yarn development in the getstarted directory, it gives an error because some files cannot be found. How should I fix these errors?
