Unable to use sass/scss/styl for styling

[animeshsinghweb]

I am able to use the simple .css but when I use .scss/.sass/.styl terminal throws me an error: TypeError: Cannot read property 'getters' of undefined.

My file structure:

.
|____xxx
| |____xxxx.pug
|____email-templates
| |____confirm-email
| | |____html.pug
| | |____style.sass

I had tried scss/styl but only simple css works.

I am using simple express routes to check if it works:

      newsletter.render(user, function (err, result) {
        if (err)
          console.log('Error while renderning confirmation newsletter: ', err);

        // result.html
        console.log('user: ', user);

        console.log(result);

        res.send(result.html);

        // result.text
      })

Help Please?

It's seems working for some reason now, don't know what was the bug, maybe there was some glitch in my code which was causing it. scss is working fine, hadn't tested less/stylus now. Therefore, closing, for now.
