npx mailing preview throws Module not found error.

When I run npx mailing preview, I get the following error. Module not found: Can't resolve './lib/beautify'

To Reproduce

Go to an empty folder

Run the following commands one by one as shown in Getting Started guide

npm install --save mailing-core next react react-dom
npm install --save-dev mailing
npx mailing --typescript
npx mailing preview

Expected behavior When I navigate to localhost:3883, I should see previews of email templates but I get the "Failed to compile" error.
