When I run npm run production or npm run package, in the process Starting 'lint'... it throws the error.

path.js:7
    throw new TypeError('Path must be a string. Received ' + inspect(path));
    ^

This project requires Node.js v4.x.x to be installed on your machine. Please be aware that you may encounter problems with the installation if you are using v5.x.x or v6.x.x

[shoaibik]

Thank you, I will try using v4 and will update the issue.

[olefredrik]

If you require different versions of Node.js for different projects, I would recommend using nvm. https://www.npmjs.com/package/nvm

[shoaibik]

Thank you, it worked after using node v4.4.3 and I used nvm.

[olefredrik]

Great! Enjoy :)
