I followed these steps to get rid of this error this does not relate to this package:

1. Run npm i -g npm
2. delete package-lock.json file
3. delete node_modules folder
4. Run npm cache clean --force
5. Run npm cache verify
6. Run npm install

I think first command do the trick but if not then try steps mentioned above.
