Answer 1

Cleaning the corrupted local npm cache may fix this error.

npm cache clean --force

Just run your npm command again after executing the above command in your terminal.

There could be few other reasons for the invalid JSON, as described in the official documentation here.

The official npm website has well documented most of the common errors. But unfortunately they don’t appear on the top results when you google the error.
