How do I start my React App After I clone it?

I'm currently trying to deploy my app with netlify, but the problem is that I clone my app into my new computer, and now I'm getting some issues.

> todolistv2@1.0.0 start /Users/hvaandres/Documents/GitHub/TodoList_React
> npm run build

I ran the following command npm install and I'm still getting the same issue. This is my debug log:
