Troubleshooting the TypeError: cli.init is not a function Error in React Native

Are you encountering the frustrating TypeError: cli.init is not a function error while trying to initialize a new React Native project after upgrading from version 0.68.2 to 0.70.1? If you're on MacOS Monterrey M1, this could be a common hiccup that developers face. But don’t worry! In this guide, we’ll guide you through understanding the problem and provide an effective solution to help you get back on track in creating your React Native applications.

Understanding the Problem

The error you see when running the command npx react-native init my-prom typically indicates that something has gone wrong in the underlying initialization process of React Native. Let’s break this down further:

Error Occurrence: The error arises due to an incompatibility or misconfiguration within the react-native-cli package after the upgrade.

Node Version: This issue may also relate to the specific version of Node.js you're currently using. In this case, Node.js v18.7.0 was mentioned.

Global vs Local Installation: Sometimes, problems related to package installations can stem from a mismatch between globally and locally installed packages.

The Solution: Fixing the Error

Based on the information provided, the solution to this issue is straightforward. Follow these steps to resolve the error:
