Solution: npm ERR! Failed to parse json

Low Risk

I would take a guess there is an error inside your `package.json` and not Express itself. What happens if you create a new project directory, run `npm init -y` and then `npm install express --save`? PS - This could be closed as it's not an Express issue.
