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": "9.0.0"
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:
回答1:
create .env file in your project file and add the following statement
SKIP_PREFLIGHT_CHECK=true
Save the file
Remove node_modules, yarn.lock, package.lock
Then reinstall node_modules with
npm install
This should work
回答2:
Part of the output you provided says:
Check if C:\Users\chawki\node_modules\babel-eslint is outside your project directory. For example, you might have accidentally installed something in your home folder.
Browse to C:\Users\chawki\node_modules\ and delete the babel-eslint folder, or simply delete C:\Users\chawki\node_modules.

I had the same problem and do all the suggested steps but the problem still, so, my error is that i have a reactApp inside other Javascript App i had this structure.
--MyProjects
----NodeJsApp
----node_modules of NodeJsApp
----package.json of NodeJsApp
----ReactApp
------node_modules of ReactApp
------package.json of ReactApp
The problem solved to me deleting my ReactApp node_modules directory, then i do a reestructure of my directories because i have a disaster.
--MyProjects
----NewDirectory (inside all about NodeJsApp)
------node_modules of NodeJsApp
------package.json of NodeJsApp
----ReactApp
------package.json of ReactApp
After that i do :
npm install
and then npm start and my problem has fixed, i think that the problem is that the parent directory cant have a javascript /nodeJs/ project or something that have node_modules .

Delete your eslint and babel-eslint file from your node modules on your computer e.g. -C:\Users\vishnu\node_modules -delete eslint and babel-eslint file.
In your project:
yarn remove eslint
yarn add --dev eslint@6.1.0
yarn remove babel-eslint
yarn add --dev babel-eslint@10.0.3
回答6:
in package.json
resolutions:{
"babel-eslint": "9.0.0"
}
if you reinstall your all dependencies, you will be forcing "babel-eslint" to be version "9.0.0". if you start your app, you will have no issue.
