How do I install it?

I'm sure you've found an alternative, which I'm curious to hear so post it here if you can, but here's how I got it working.

1. In the node_modules folder, make a folder called 'react-native-horizontal-scroll-picker'
2. download all the code in this repository and paste it in that folder
3. in the file you want to use it in, import the way it's detailed:

import {HorizontalScrollPicker} from 'react-native-horizontal-scroll-picker';
import _ from 'lodash';

4. just use it and edit the styles as you want

...
<HorizontalScrollPicker
          items={emoNumItems}
          textStyle={styles.emoSelect}
          selectedTextStyle={styles.emoSelected}
          containerStyle={styles.scrollPickerContainer}
          itemStyle={styles.item}
          selectorStyle={styles.selectedItem}
          onSelect={(selectI) => this.setState({selectedItem: selectI})}
          initialIdx={0}
        />
...
const styles = StyleSheet.create({
item: {
    textAlign: 'center',
    textAlignVertical: 'center',
    color: '#000',
    fontSize: 18,
  },
  selectedItem: {
    flex: 1,
    position: 'absolute',
    top: 0,
    backgroundColor: 'transparent',
    borderWidth: 0, //indicator line
    borderColor: '#000',
    borderRadius: 12,
  },
  emoSelect: {
    fontFamily: 'AGaramondPro-Regular',
  },
  emoSelected: {
    fontFamily: 'AGaramondPro-Regular',
    fontWeight: 'bold',
  },
});

I changed up the default values a bit for myself so you can just interpret my changes from the original given code.
