[SOLVED] 'lite-server' is not recognized as an internal or external command, operable program or batch file

I'm having this error during running the following command on Windows 10.

npm run dev

I'm running lite-server on windows 10, I have tried to solve it using the following commands

npm install -g npm-windows-upgrade
npm install -g concurrently

although I have tried to remove package.json and node modules, reinstalling nodejs. but it seems it is not working.

CMD Err running npm run dev logfile as in the following
