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:
"babel-eslint": "10.0.2"
Don't try to install it manually: your package manager does it automatically. However, a different version of babel-eslint was detected higher up in the tree:
C:\\Users\\Samson Adedayo\\Desktop\\node_modules\\babel-eslint (version: 10.0.1)
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:
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\\Samson Adedayo\\Desktop\\node_modules\\babel-eslint is outside your project directory. For example, you might have accidentally installed something in your home folder.
Try running npm ls babel-eslint in your project folder. This will tell you which other package (apart from the expected react-scripts) installed babel-eslint.
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.
PS We know this message is long but please read the steps above :-) We hope you find them helpful!

I was having this same issue. Occasionally the create-react-app does not install its dependencies correctly. To solve this I did the following:
To do this add "babel-eslint": "10.0.2"
to the end of your dependencies list
npm i
and you should be good to goCreate .env
file in your react-app folder and paste below line in it
SKIP_PREFLIGHT_CHECK=true
your problem will get solve
