Not able to create new app using the "create-react-native-app"

I have never encountered any issue in all my time creating react-native apps using the "create-react-native-app" cli command until today. It didn't create the usual ios and android file it creates but instead only create the node_modules, package-lock.json and package.json files. Below is the output i got back when i ran the command.

    $ create-react-native-app Rdx
Creating a new React Native app in /Users/apple/Documents/Vscode/Redux-Testing/Rdx.

Using package manager as npm with npm interface.
Installing packages. This might take a couple minutes.
Installing react-native-scripts...

npm notice created a lockfile as package-lock.json. You should commit this file.

The version of create-react-native-app that you are using is quite old. It uses react-native-scripts instead of Expo SDK.

You need to use the correct version of react-native-scripts. You can do this by specifying the correct react-native-script version when creating a new project with create-react-native-app. To find the correct version of react-native-scripts, first find out the version of create-react-native-app using the command:

create-react-native-app --version

Next see the Changelogs for both create-react-native-app and react-native-scripts.

Choose a version of react-native-scripts that was released around same time as your version of create-react-native-apps.

After that specify the version of react-native-scripts when creating a new project with create-react-native-app. For example:

create-react-native-app --scripts-version 1.4.0 project-name

Its because react-native-scripts package is old which is used by create-react-native-app may be now your version create-react-native-app will be version: 1.0.0.

update the package.

npm install -g create-react-native-app

now create-react-native-app version will be 2.0.2.

You are now ready to create your app.

create-react-native-app Rdx

You may asked to install expo-cli say Y.

Another good thing in create-react-native-app 2.0.2 is you can create blank or tabs app. use arrow keys to select your preferred app in terminal.
