VisualizaçõesFacing an Error when installing create-react-app package from npm
I'm trying to install React on my Computer. I'm a beginner and installing it for the first time. However, when I used create-react-app react-app to start a project, it showed the following: 
But the app is working fine, I launched the server through npm start and it works, so should I ignore these errors or not?

the first warning you get (deprecated) means that one of the packages you are using (in this case - source-map-resolve) was deprecated (i.e is not maintained). you can go to the package GitHub repo to find a way to resolve it.
the second error you get (cannot read properties of undefined) tells you that there is a difference between versions of global packages. sometimes restarting your wifi helps it, or updating NPM/windows/node/all your packages

run npm audit fix and see if that helps. If not then i would just continue working on your project. Since you're a beginner you will learn more about NPM as you work. Npm is notorious for installing a ton of dependencies that are deprecated.
