The react-scripts package provided by Create React App requires a dependency:

Question

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:

Solution 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

Solution 2

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 .

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.

Solution 4

I just deleted the node_modules folder (for me it was C:\user\[yourUserName]\node_modules\) and re-installed it.

Solution 5

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 [email protected]

yarn remove babel-eslint
yarn add --dev [email protected]
