Traccar Modern Interface Source Code

I am running traccar web from source code but moder interface not working, nor it is showing link in for modern interface or not loading even going directly to url. Getting 404 Not Found on modern interface.
Please confirm what are the requirements to run modern interface.
Also when I run npm install in modern web directory getting below error

npm ERR! code 127
npm ERR! path C:\traccar\traccar-web\modern\node_modules\babel-runtime\node_modules\core-js (looks like path is wrong)
npm ERR! command failed
npm ERR! command bash -c node -e "try{require('./postinstall')}catch(e){}"
npm ERR! /bin/bash: node: command not found

Looks like you don't have node on your path, as the error message indicates.

Now getting below error.

While resolving: traccar@0.1.0
Found: react@17.0.2
node_modules/react
  react@"^17.0.2" from the root project

Could not resolve dependency:
peer react@"^0.14.0 || ^15.0.0 || 16.x" from react-container-dimensions@1.4.1
node_modules/react-container-dimensions
  react-container-dimensions@"^1.4.1" from the root project

Fix the upstream dependency conflict, or retry
this command with --force, or --legacy-peer-deps
to accept an incorrect (and potentially broken) dependency resolution.

I think there is some issue in node version, I am using latest node and getting error which is mentioned in previouse post, downgraded node to version 12 and now getting below error.

npm ERR! code ELIFECYCLE
npm ERR! syscall spawn
npm ERR! file bash
npm ERR! errno ENOENT
npm ERR! core-js@2.6.12 postinstall: `node -e "try{require('./postinstall')}catch(e){}"`
npm ERR!
npm ERR! Failed at the core-js@2.6.12 postinstall script.

Can you confirm which version should I use.
