I resolved it by deleting node_modules and package-lock.json and run npm install again.

Probably it's a project that works with Yarn and not NPM. Try Yarn instead of NPM.

yarn install

and then you can do

yarn start

or

npm start

I was getting the same error, but I was able to resolve it by the below described method:

Go to folder -> Local > npm-cache and delete all contents of the npm-cache. try again with npm command, it should work now.
