Step 3: Check for Additional Issues

If you still face the error, consider checking for these common issues:

Multiple React Instances: Confirm that there is only one instance of React in your project dependencies. Sometimes, dependencies can inadvertently install a separate version of React.

Mismatched Versions: Ensure that react and react-dom versions are compatible with the version of react-router-dom you are using.

Using Hooks Correctly: Make sure any hooks like useState, useEffect, or others are being called inside functional components only.

Conclusion

The "Invalid hook call" error can often feel overwhelming but is usually indicative of a simple issue in your project setup. By ensuring that you have react-router-dom installed and checking your code implementation, you can resolve these issues and have a functioning router in your application.

Remember, it's crucial to always check your package installations and the way you structure your component hierarchy when dealing with hooks in React. With these steps, you should be well on your way to a successful, error-free routing experience in your React app!
