Module not found: Can't resolve 'styled-components' in '/home/user/project/node_modules/react-vertical-tree/dist'

Installed the package and compiled the app. Got this compilation error.

I had a similar issue, and I just had to install the 'styled-components':
npm install styled-components --save
fixed it for me!
