i included mocha and should in package.json but why i am facing this error .should is showing in my node modules also.please guideline

Answer 1

I faced the same issue, and I think it is because should package has been updated two hours ago (and it may have broken something).

npm install should@1.3.0

did the trick.

EDIT

Version 2.0.1 fixed the issue.

Answer 2

It simply means should from the NPM is not installed. Simply use

sudo npm install should  

This means that it should install should from the node package manage.

Hope it makes stuff clearer.

Cheers.
