Problem with the start script

[sdabhi23]

I have npm v5.5.1 and node v8.9.1 installed on my machine.
When I run npm start it gives the following error:

> hasura-week1@1.0.0 start C:\Users\Shrey\Desktop\Hasura-Week1
> nodemon app

'nodemon' is not recognized as an internal or external command,
operable program or batch file.
npm ERR! code ELIFECYCLE

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
