Solved: Error: Failed to Load Plugin ‘react’ Declared in ‘.eslintrc.js’: Cannot Find Module ‘eslint-plugin-react’

If you’re reading this article, chances are you’re frustrated with the infamous error message that’s been haunting your code editor:

Error: Failed to load plugin 'react' declared in '../.eslintrc.js': Cannot find module 'eslint-plugin-react'

Don’t worry, friend! You’re in the right place. In this comprehensive guide, we’ll embark on a journey to troubleshoot and resolve this pesky issue once and for all.

What’s the Deal with ESLint and Plugins?

Before we dive into the solution, let’s take a step back and understand the context. ESLint is a popular JavaScript linter that helps developers maintain code quality by identifying errors, enforcing coding standards, and providing suggestions for improvement. Plugins are essential components that extend ESLint’s capabilities to support specific features, frameworks, or libraries.

In this case, the error message is complaining about the ‘react’ plugin, which is specifically designed for React applications. The plugin provides a set of rules to ensure your React code is clean, maintainable, and follows best practices.

Why is ESLint Failing to Load the ‘react’ Plugin?

There are a few reasons why ESLint might fail to load the ‘react’ plugin:

• Missing or incorrect plugin installation: The ‘eslint-plugin-react’ package might not be installed or installed incorrectly, leading to the error.
• Invalid or outdated plugin configuration: The ‘.eslintrc.js’ file might contain incorrect or outdated configuration for the ‘react’ plugin.
• Conflicting plugin versions: Incompatible plugin versions can cause issues, especially if you’re using multiple plugins that rely on different versions of ‘eslint-plugin-react’.
• Corrupted or outdated Node.js or ESLint installation: A faulty Node.js or ESLint installation can lead to plugin loading issues.

Troubleshooting Steps to Resolve the Error

Now that we’ve covered the possible causes, let’s walk through the troubleshooting steps to resolve the error:

1. Verify Plugin Installation:

   npm ls eslint-plugin-react

   or

   yarn ls eslint-plugin-react

   Check if the ‘eslint-plugin-react’ package is installed and listed in your project’s dependencies. If not, install it using:

   npm install eslint-plugin-react

   or

   yarn add eslint-plugin-react

2. Check ‘.eslintrc.js’ Configuration:

   Open your ‘.eslintrc.js’ file and ensure the ‘react’ plugin is correctly configured:

   module.exports = {
     // ...
     plugins: {
       react: {
         version: 'detect', // or specify a specific version
       },
     },
     // ...
   };

   Make sure the ‘react’ plugin is listed in the plugins object, and the version is set to ‘detect’ or a specific version that matches your project’s requirements.

3. Check for Conflicting Plugin Versions:

   Run the following command to check for conflicting plugin versions:

   npm ls eslint-plugin-react eslint

   or

   yarn ls eslint-plugin-react eslint

   If you notice any version conflicts, try updating or downgrading the plugins to compatible versions.

4. Update Node.js and ESLint:

   If you’re running an outdated version of Node.js or ESLint, update them to the latest versions:

   nvm install node

   or

   nvm install latest

   npm install eslint@latest

   or

   yarn add eslint@latest

5. Delete ‘node_modules’ and Reinstall Dependencies:

   As a last resort, try deleting the ‘node_modules’ directory and reinstalling your project’s dependencies:

   rm -rf node_modules

   or

   rmdir /s /q node_modules

   Followed by:

   npm install

   or

   yarn install

Additional Tips and Recommendations

To avoid future issues, consider the following tips and recommendations:

• Keep your dependencies up-to-date: Regularly update your project’s dependencies to ensure you’re using the latest versions of plugins and libraries.
• Use a consistent plugin configuration: Establish a consistent plugin configuration across your project to avoid version conflicts and ensure seamless integration.
• Monitor ESLint errors and warnings: Keep an eye on ESLint errors and warnings to identify issues early on and prevent them from accumulating.
• Explore alternative linters and plugins: If you’re experiencing persistent issues with ESLint, consider exploring alternative linters like TSLint or JSLint, or plugins like Prettier.

Scenario	Solution
Missing ‘eslint-plugin-react’ package	Install the package using npm or yarn
Invalid ‘.eslintrc.js’ configuration	Verify and correct the plugin configuration in ‘.eslintrc.js’
Conflicting plugin versions	Update or downgrade plugins to compatible versions
Outdated Node.js or ESLint installation	Update Node.js and ESLint to the latest versions
Corrupted ‘node_modules’ directory	Delete ‘node_modules’ and reinstall dependencies
