unable to yarn install in ubuntu(fsevents@1.2.4: The platform "linux" is incompatible with this module)

I cloned a project from Github and following the initial instructions, it shows this error described below.

I tried to understand it and google it, and from there I changed my NodeJS version multiple times using nvm but the problem is not resolved, the error is not getting fixed.

Screenshot:

You're looking for the wrong thing :) fsevents is optional and you don't need to worry about it. Instead focus on this one:

error get-caller-file@2.0.1: The engine "node" is incompatible with this 
module. Expected version "6.* || 8.* || >= 10.*". error An unexpected 
error occurred: "Found incompatible module".

The error is pretty descriptive. Please install the correct node version and you're good to go! If you have trouble with conflicting node versions (in case you're working on several projects with separate requirements), head over to: https://github.com/creationix/nvm and install nvm in order to manage multiple node installations in parallel.
