NativeBase setup/installation error - node.js

Question

I am trying to setup/install Native-Base in my React-Native project using the official document. But getting error every time.
Command: npm install native-base --save
Error:
npm ERR! Unexpected end of JSON input while parsing near '...yish/-/is-arrayish-0.'
npm ERR! A complete log of this run can be found in:
npm ERR! /home/abhijitsrivastava/.npm/_logs/2018-07-04T06_03_24_057Z-debug.log
System Specification:
node --version
v8.1.0
npm --version
6.0.0
react-native --version
react-native-cli: 2.0.1
react-native: 0.55.4
Machine: Ubuntu 16.04LTS
IDE: Visual Studio Code Version 1.23.0
As per the compatibility matrix every thing is looking OK. I don't know how can I fix it.
Update :
Here is my package.json file.
{

}

Answer 1

I have noticed in a recent forum post where they've recommeneded to use yarn in place of npm for installing the dependencies and for creating the react native app.
Yarn: https://yarnpkg.com/en/docs/install#windows-stable
After installing yarn try issuing the below command,
yarn add native-base --save
Hope this helps!

To solve this issue you can try to change your node js version
npm install native-base this is giving issue with 18.7.0 version but
change to
