Answer 1

It is an error in node. It works with carrying out 3 steps 1.- Uninstall and reinstall the (last) version of the node 2.- Inside the project, delete the package-lock.json file (it will be automatically regenerated) and the node_modules folder 3.- run npm install to reload the node_modules
