Solutions to the “[ERR_MODULE_NOT_FOUND]: Cannot find package ‘eslint-plugin-react'” Error

Now that we’ve identified the causes, let’s get to the good stuff – solving the error!

Solution 1: Install the eslint-plugin-react Package

The most straightforward solution is to install the eslint-plugin-react package using npm or yarn:

npm install eslint-plugin-react --save-dev

yarn add eslint-plugin-react --dev

This will install the plugin as a development dependency, ensuring it’s only used during development and not included in your production build.

Solution 2: Verify ESLint Configuration

Check your ESLint configuration file (usually .eslintrc.json or .eslintrc.js) to ensure the eslint-plugin-react plugin is properly configured:

{
  "plugins": {
    "react": {
      "version": "7.24.0"
    }
  }
}

Make sure the version of the plugin matches the one installed in your project.

Solution 3: Check for Version Conflicts

Version conflicts can cause the error, so ensure that your eslint-plugin-react version is compatible with your project’s dependencies. You can check the versions using:

npm ls eslint-plugin-react

Update the package to the latest version or a compatible version that fits your project’s needs.

Solution 4: Reinstall Packages

In some cases, reinstalling packages can resolve the issue. Try removing the node_modules directory and reinstalling packages:

rm -rf node_modules
npm install

This will reinstall all packages, including the eslint-plugin-react plugin.

Solution 5: Update Node.js and npm

Outdated versions of Node.js and npm can cause issues. Ensure you’re running the latest versions:

npm install -g n
n latest
npm install -g npm@latest

This will update Node.js and npm to the latest versions.
