Error on strating with zip

Hello all after downloading and extracting the zip ‘m220/’ from the course.
I am getting bellow error with
‘npm start’.

PS D:\Learning R&D\mflix-js> npm start

server@1.0.0 start D:\Learning R&D\mflix-js
nodemon -L ./index.js

‘D\mflix-js\node_modules.bin’ is not recognized as an internal or external command,
operable program or batch file.
throw err;

Error: Cannot find module ‘D:\nodemon\bin\nodemon.js’
at Function.Module._load (internal/modules/cjs/loader.js:687:27)
at Function.Module.runMain (internal/modules/cjs/loader.js:1025:10)
at internal/main/run_main_module.js:17:11 {

what could be the issue ? as i can see it can not find some entry point js for the application.
can any one help me out from this problem?

Have you install the requirements with npm install?
