I am trying to install Realm for my React native app and I get the following error, could you suggest what might be wrong.

I am using the command 

npm install --save realm

from the web - https://realm.io/docs/javascript/latest/

Error: 

npm ERR! Failed at the realm@2.11.0 install script.

I have tried to install 

npm install -g node-pre-gyp

and

npm install -g node-gyp

Still did not work. any suggestions would be very helpful

Thanks R

here is my log

    npm install --save realm

Thanks @Ashwin Mothilal, I had to go back to a stable version of Node (v8.11.3). How I did it.

It took a while to figure out the entire procedure, writing down the steps I performed. Hope this helps

1 - Uninstalled Node.js completely from my machine. (Windows) Followed this link - [How to completely remove node.js from Windows (Dont forget to restart your PC)

2 - Downloaded and Installed the stable version (8.11.3 LTS) from - [https://nodejs.org/en/][1]

3 - Restart your machine.

4 - Check the node version now (>> node -v).

5 - In your project remove all node_modules - rm -rf node_modules/ npm install link - [How to clean node_modules folder of packages that are not in package.json?

6 - then do - >>npm install in your project. This should install all the required dependencies.

7 - Now install Realm.

npm install --save realm

This has successfully added Realm to my project.

Note: When I was getting this errors which I have posted in my actual question, It recommended me to install 'node-pre-gyp'. I tried to install 

  npm install --save node-pre-gyp --fallback-to-build
  npm install --save node-pre-gyp
  npm install -g node-pre-gyp

Which did not work, so Before I did the steps provided above I have removed 'node-pre-gyp'. In case you have installed any of the above you can please remove them as it was not required.

Hope this helps. R

1) First Check Node version using below command

node -v
v10.16.0

If Version is not match with 10.16.0 than install node using below link

https://nodejs.org/en/download/

and install node 10.16.0

Blockquote

Install realm using below command

npm install --save realm

Realm install successfully.!!!
