how to integrate webpack with the existing react project - reactjs

Question

I have a react project and I want to bundle it using webpack. I have set up the entry, output, path, and filename etc,. But, doing so, when I am running the project I get the following errors. How can I solve this.
There might be a problem with the project dependency tree. It is
likely not a bug in Create React App, but something you need to fix
locally.
The react-scripts package provided by Create React App requires a
dependency:
"webpack": "4.42.0"
Don't try to install it manually: your package manager does it
automatically. However, a different version of webpack was detected
higher up in the tree:
C:\Users\gowtham\Desktop\task\node_modules\webpack (version: 4.42.1)
Manually installing incompatible versions is known to cause
hard-to-debug issues.
If you would prefer to ignore this check, add
SKIP_PREFLIGHT_CHECK=true to an .env file in your project. That will
permanently disable this message but you might encounter other issues.
To fix the dependency tree, try following the steps below in the exact
order:
Delete package-lock.json (not package.json!) and/or yarn.lock in your project folder.
Delete node_modules in your project folder.
Remove "webpack" from dependencies and/or devDependencies in the package.json file in your project folder.
Run npm install or yarn, depending on the package manager you use.
In most cases, this should be enough to fix the problem. If this has
not helped, there are a few other things you can try:
If you used npm, install yarn (http://yarnpkg.com/) and repeat the above steps with it instead.
This may help because npm has known issues with package hoisting which may get resolved in future versions.
Check if C:\Users\gowtham\Desktop\task\node_modules\webpack is outside your project directory.
For example, you might have accidentally installed something in your home folder.
Try running npm ls webpack in your project folder.
This will tell you which other package (apart from the expected react-scripts) installed webpack.
If nothing else helps, add SKIP_PREFLIGHT_CHECK=true to an .env file
in your project. That would permanently disable this preflight check
in case you want to proceed anyway.
P.S. We know this message is long but please read the steps above :-)
