[Gatsby Build] window is not defined

[QasimRRizvi]

I'm trying to build my website with gatsby build command but end up on this error

WebpackError: ReferenceError: window is not defined
  
  - react-bootstrap-carousel.js:1 Object../node_modules/react-bootstrap-carousel    /dist/react-bootstrap-carousel.js
    node_modules/react-bootstrap-carousel/dist/react-bootstrap-carousel.js:1:1
  
  - servicesSlider.js:1 Module../src/components/servicesSlider.js
    src/components/servicesSlider.js:1:1

    src/components/index.js:1:1
  
  - 404.js:1 Module../src/pages/404.js

Any help would be great!
