Missing binding error

Appflow
#1

I am trying to build an app in Ionic Pro and getting this error message.

Error: Missing binding /usr/src/app/node_modules/node-sass/vendor/linux-x64-57/binding.node
Node Sass could not find a binding for your current environment: Linux 64-bit with Node.js 8.x

Found bindings for the following environments:
  - OS X 64-bit with Node.js 8.x

I tried running

sudo npm rebuild node-sass

in the root directory but it did not cure the problem.

How can I solve this issue? I would like to use Ionic Pro to help publish, monitor, and deploy live updates but I got stuck here.

Thanks,
