Your package.json file has a syntax error. For finding the error use JSON validator, for example, jsonlint.com. Also, every modern IDE has auto-validating features.

This solved it for me:

1. Clean your npm cache

run this command in your project root folder:

npm cache clean --force

2. Delete package.lock.json

3. Delete node_modules folder

run again

npm install
