Will this be an issue for continuing the course??

And I follow through , then when I type npm start on the terminal I got this error.

**chamoddeshan@Chamods-iMac react-app % npm start**  
**npm ERR! missing script: start**

**npm ERR! A complete log of this run can be found in:**  
**npm ERR! /Users/chamoddeshan/.npm/\_logs/2021-09-25T11\_08\_25\_695Z-debug.log**  
**chamoddeshan@Chamods-iMac react-app %**

How can I fix them inorder to follow the course? Thanks!

The deprecation warning is because you are using an old version of create-react-app and its dependencies. I don’t think it will prevent you from continuing the course.

As for the missing script error, have you run create-react-app to create your React app yet?

The course that I’m reviewing right now states to use “npx create-react-app [insert name of your app]”. That’s the best way to do it.

Npm command doesn’t work anymore for some reason.

Happy reacting. 🤠
