You probably just got an installation error. Try deleting the node_modules folder and npm installing again.

@sajjadmurtaza49 You definitely have errors as you installed npm dependencies according to your error message. Installation has not been completed well. Firstly, check your environments of npm / node then make sure that install dependencies with no errors.
