I hope you guys can help me to point out where i should make changes so it can work successfully. thanks in advance !

Have you tried nuking the node_modules folder and installing again? rmdir ./node_modules and npm install. Also, what node version are you on? node -v — n8jadams

after creating a project with create-react-app

create-react-app name

you have to go inside the created folder

cd name

and then run

npm start

again
