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

Error:
npm ERR! Failed at the realm#2.11.0 install script.
I have tried to install
npm install -g node-pre-gyp

npm install -g node-gyp
Still did not work. any suggestions would be very helpful

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.

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
Install realm using below command
npm install --save realm
Realm install successfully.!!!
