package.json must be actual JSON, not just JavaScript

json node.js express npm

Just type npm cache clean on prompt and all the things must to work again.

json node.js express npm

package.json file should not be empty.

If you have empty package json file just add {}.

and try again.

json node.js express npm

You have curly quotes before the 4 - “4.6.1". Change that to a regular quote character and it'll pass.
