So the best thing to do is to remove create-react-app globally using npm uninstall create-react-app -g or yarn global remove create-react-app because that is likely the reason you're seeing this error message:

This is likely because you're using an outdated version of create-react-app. Please note that global installs of create-react-app are no longer supported.

Once you've removed it, please note you don't need to install create-react-app globally to initialize a new project, its recommended you use the npx package runner tool that comes with at least node 5.2 and above. So npx will basically allow you to run a package without installing it, so on your case create-react-app.

So to create a new project, just type in : npx create-react-app myapp and that will initialize your react app.
