React Native Command Prompt npm issue

My Command Prompt problem in react native
C:\Users\nagaraju\albums>react-native start
Command ‘start’ unrecognised.Make sure that you have run ‘npm install’ and that you are inside a react-native project

how to solve these issue…

Does it display a start script in the package.json file? Also, check and make sure that you’re in the right directory. You have to be pointed to the right directory with your command prompt or terminal before you can run the command.

can you send me Command Process…
