Hi there,

MODULE_NOT_FOUND errors imply you haven’t installed your dependencies. Either at all, (e.g. missing npm install) or that the package is in your devDependencies and you need to either move it to dependencies or include the devDependencies in your install (npm install docs)

Hope that helps
