I have installed nodejs exe from website.  
used this command : npm install -g --unsafe-perm node-red  
THEN started "Node-red" in command prompt and tried installing modbus node.  
npm install node-red-contrib-modbus  
Can anyone give me a fix for it ?

You have to run the **Npm install node-red-contrid-modbus** from within your node red directory.  
Most likely **`C:\users\rverma\node-red`**  
Or install it from the pallet manager in Node-red dashboard, much easier.

You have spelled the node name wrong,. you have `contrid` and it is `contrib` a 'b' at the end, not a 'd'

HI,  
If you see the line number 13 in image, You will se that i have written the correct command.  
It is strange for me because I have installed it in another laptop and it worked as it does generally.

In future please copy/paste terminal output rather than screenshot. That makes it much easier for us

It is what you took a screenshot of showing the errors. Copy/paste of the text is better than a screenshot.
