return an error when I import NavigationBar

I have used npm installed Navigation Bar to my project
`$ npm install react-native-navbar --save`
After I add this line to my Home.js, it return the error as attachment
`import NavigationBar from 'react-native-navigation-bar';`

Start with the npm install command and the import in Home.js, noting that they name different packages. Reproduce the reported import error using the stated installation, then confirm the package and import reference are consistent and document the resulting behavior.
